Logging in western North America impacts populations of western trillium, a long-lived perennial that inhabits confider forests (Trillium ovatum). Jules and Ratchke (1999) measured attributes of eight local populations of western trillium, confined to forest patches of varying size created by logging in southwestern Oregon. Their data, presented in the following table, compares estimates of recruitment (the density of new plants produced in each population per year) at each site with the distance from the site to the edge of the forest fragment.

a. Display these data in an appropriate graph. Examine the graph and describe the shape of the distribution. What departures from the assumption of correlation analysis do you detect?

b. Choose a transformation and transform one or both of the two variables. Plot the results. Did the transformation solve the problem? If not, try a different transformation.

c. Using the transformed data, estimate the correlation coefficient between the two variables. Provide a standard error with your estimate.

d. Calculate an approximate 95% confidence interval for the correlation coefficient.

The Kaumajet Factory produces two products - table lamps and desk lamps. It has two separate departments - Finishing and Production. The overhead budget for the Finishing Department is $700,050, using 359,000 direct labor hours. The overhead budget for the Production Department is $330,546 using 61,900 direct labor hours.

If the budget estimates that a desk lamp will require 5 hours of finishing and 8 hours of production, what is the total amount of factory overhead the Kaumajet Factory will allocate to desk lamps using the multiple production department factory overhead rate method with an allocation base of direct labor hours, if 10,000 units are produced?

a.$318,312

b.$166,480

c.$53,400

Java Coding Program.

In this assignment, you will write a program that analyzes Phoenix area 2018 rainfall data. Inside the main() method, first you will get the rainfall data for each of the 12 months in 2018 from the user and stores them in a double array. Next, you will need to design the following four value-returning methods that compute and return to main() the totalRainfall, averageRainfall, driestMonth, and wettestMonth. The last two methods return the index (or number) of the month with the lowest and highest rainfall amounts, not the amount of rain that fell those months. Notice that this month index (or number) can be used to obtain the amount of rain that fell those months.

I need help with driestMonth and wettestMonth. Wettest month is not giving me the correct output.

This is how it should read when it prints out on screen. Example : "The least rain fell in May with 0.35 inches."

This is what I have so far.

An asset manager follows an active international asset allocation strategy. The average execution cost for a buy or a sell order is forecasted at 0.6%. On average, the manager turns over the portfolio once a year. Various administrative costs include a custodial cost amount of 0.5% per year of assets under management. The annual management fee is 1% of assets under management. The annual expected return before costs is 14% compared to an expected return of 10% on a passive global benchmark (some global index).
1. What is the annual expected return net of execution costs?
2. What is the net annual expected return for the client?
3. Should the client expect the portfolio to outperform the global index used as a benchmark?

HOW STARBUCKS USES PRICING

STRATEGY FOR PROFIT

MAXIMIZATION

Value Based Pricing Can Boost Margins

For the most part, Starbucks is a master of employing value based pricing to maximize profits, and they use research and customer analysis to formulate targeted price increases that capture the greatest amount consumers are willing to pay without driving them off. Profit maximization is the process by which a company determines the price and product output level that generates the most profit. While that may seem obvious to anyone involved in running a business, it’s rare to see companies using a value based pricing approach to effectively uncover the maximum amount a customer base is willing to spend on their products. As such, let’s take a look at how Starbucks introduces price hikes and see how you can use their approach to generate higher profits.

An Overview of the Starbucks Pricing

Strategy:

The Right Customers and the Right Market

While cutting prices is widely accepted as the best way to keep customers during tough times, the practice is rarely based on a deeper analysis or testing of an actual customer base. In Starbucks’ case, price increases throughout the company’s history have already deterred the most price sensitive customers, leaving a loyal, higher-income consumer base that perceives these coffee beverages as an affordable luxury. In order to compensate for the customers lost to cheaper alternatives like Dunkin Donuts, Starbucks raises prices to maximize profits from these price insensitive customers who now depend on their strong gourmet coffee.

Rather than trying to compete with cheaper chains like Dunkin, Starbucks uses price hikes to separate itself from the pack and reinforce the premium image of their brand and products. Since their loyal following isn’t especially price sensitive, Starbucks coffee maintains a fairly inelastic demand curve, and a small price increase can have a huge positive impact on their margins without decreasing demand for beverages. In addition, only certain regions are targeted for each price increase, and prices vary across the U.S. depending on the current markets in those areas (the most recent hike affects the Northeast and Sunbelt regions, but Florida and California prices remain the same).

Product Versioning & Price Communication

They also apply price increases to specific drinks and sizes rather than the whole lot. By raising the price of the tall size brewed coffee exclusively, Starbucks is able to capture consumer surplus from the customers who find more value in upgrading to Grande after witnessing the price of a small drip with tax climb over the $2 mark. By versioning the product in this way, the company can enjoy a slightly higher margin from these customers who were persuaded by the price hike to purchase larger sizes.

Starbucks also expertly communicates their price increases to manipulate consumer perception. The price hike might be based on an analysis of the customer’s willingness to pay, but they associate the increase with what appears to be a fair reason. Using increased commodity costs to justify the price as well as statements that aim to make the hike look insignificant (less than a third of beverages will be affected, for example) help foster an attitude of acceptance.

on Wednesday April 8, Starbucks announced that it expects its fiscal second-quarter earnings to be cut nearly in half as the coronavirus pandemic causes sales to plunge in its two largest markets.

For this assignment, we will learn to use Python's built in set type. It's a great collection class that allows you to get intersections, unions, differences, etc between different sets of values or objects.

1. Create a function named common_letters(strings) that returns the intersection of letters among a list of strings. The parameter is a list of strings.

For example, you can find the common letter in the domains/words statistics, computer science, and biology. You might easily see it, but you need to write Python code to compute the answer. In order to pass the tests you must use the set api.

Consider the cell described below at 261 K:

Fe | Fe²⁺ (0.903 M) || Cd²⁺ (0.991 M) | Cd

Given E^o_Cd²⁺→Cd = -0.403 V, E^o_Fe²⁺→Fe = -0.441 V. Calculate the cell potential after the reaction has operated long enough for the Fe²⁺ to have changed by 0.373 mol/L

Assume two neighbors who live next to a pond. Both neighbors get together to determine how each of them value a large deck overseeing the pond. After some economic analysis, they arrive at the following demand estimates: Qa = 160 − 20Pa , Qb = 60 − 5Pb where Q is the size of the deck to be built and P is the price of inputs and labor.

a) Based on these estimates, determine the market demand (assuming these are the only two households living next to the pond) for this public good, the deck overlooking the pond. Draw three graphs on the top of each other -first graph for A’s demand, a second graph for B’s demand, and the third graph for the market demand.

b) Explain the shape of the demand curve. Determine the willingness to pay when the size of the pond is 60 square feet.

c) If the market supply for pond decks were P= 6 + 0.15Q, what would be the optimal provision of this public good, that is what would the size of the pond?

d) Which neighbor is more likely to build the pond? Explain your answer.

on January 2nd 2016 the Jackson company purchased equipment to be used in its manufacturing process the equipment has an estimated life of 8 years and an estimated residual value of $30,625 expenditures made to acquire the assets were as follows

purchase price $154,000
Freight charges $2,000
installation charges $4,000

Jackson's policy is to use the double declining balance method of depreciation in the early years of the equipment's life and then switch to straight line halfway through the equipments life.

1. calculate depreciation for each year of the assets eight-year life

2. discuss the accounting treatment of the depreciation on the equipment

Personal Trainer, Inc. owns and operates fitness centers in a dozen Midwestern cities. The centers have done well, and the company is planning an international expansion by opening a new “supercenter” in the Toronto area. Personal Trainer’s president, Cassia Umi, hired an IT consultant, Susan Park, to help develop an information system for the new facility. During the project, Susan will work closely with Gray Lewis, who will manage the new operation. Background During requirements modeling for the new system, Susan Park met with fitness center managers at several Personal Trainer locations. She conducted a series of interviews, reviewed company records, observed business operations, analyzed the BumbleBee accounting software, and studied a sample of sales and billing transactions. Susan’s objective was to develop a list of system requirements for the proposed system.

Fact-Finding Summary

• A typical center has 300–500 members, with two membership levels: full and limited. Full members have access to all activities. Limited members are restricted to activities they have selected, but they can participate in other activities by paying a usage fee. All members have charge privileges. Charges for merchandise and services are recorded on a charge slip, which is signed by the member. • At the end of each day, cash sales and charges are entered into the BumbleBee accounting software, which runs on a computer workstation at each location. Daily cash receipts are deposited in a local bank and credited to the corporate Personal Trainer account. The BumbleBee program produces a daily activity report with a listing of all sales transactions. • At the end of the month, the local manager uses BumbleBee to transmit an accounts receivable summary to the Personal Trainer headquarters in Chicago, where member statements are prepared and mailed. Members mail their payments to the Personal Trainer headquarters, where the payment is applied to the member account. • The BumbleBee program stores basic member information, but does not include information about member preferences, activities, and history. • Currently, the BumbleBee program produces one local report (the daily activity report) and three reports that are prepared at the headquarters location: a monthly member sales report, an exception report for inactive members and late payers, and a quarterly profitand-loss report that shows a breakdown of revenue and costs for each separate activity. During the interviews, Susan received a number of “wish list” comments from managers and staff members. For example, managers want more analytical features so they can spot trends and launch special promotions and temporary discounts. Managers also want better information about the profitability of specific business activities at their centers, instead of bottom-line totals. Several managers want to offer computerized activity and wellness logs, fitness coaching for seniors, and various social networking options, including e-mail communications, fitness blogs, Facebook, and Twitter posts. Staff members want better ways to handle information about part-time instructors and trainers, and several people suggested using scannable ID cards to capture data

Tasks

1. Draw a DFD that shows how data will be stored, processed, and transformed in the TIMS system.

2. Draw an FDD that shows the Personal Trainer’s main functions. Also draw a use case diagram that represents the interaction between a user and the proposed TIMS system.

3. Using the information gathered during fact-finding, develop a requirements checklist that includes examples in each of the five main categories.

4. Gray is not familiar with the TCO concept. How should Susan explain it to him?
