9. An analyst believes that long-distance running reduces muscle mass. She collects data on subjects (pounds of muscle mass, hours of running per week, and calories consumed per week) and performs a regression. Here are the results:

Interpret the RUNNING coefficient:

a. Running one more hour per week will reduce calories by 3.5

b. People with greater muscle mass run than

3.5 less miles per week

c. Running more than 3.5 miles per week will reduce muscle mass

d. Running one more hour per week will reduce muscle mass by 3.5 pounds

Is the Running variable statistically significant?

a. Yes

b. No

If Frank runs 3 hours per week and consumes 12,000 calories per week, estimate his weight with the regression model..?

If the coefficient of determination (R2) is 0.76 for this regression, this means that

a.24 percent of the variation in the dependent variable is explained by the regression.

b.24 percent of the variation in the independent variable is explained by the regression.

c.76 percent of the variation in the dependent variable is explained by the regression.

d.76 percent of the variation in the independent variable is explained by the regression

Cost Benefit Analysis over 10 years

Do a cost benefit analysis to decide wheteher to switch from a gas car to an electric car.

HINT: Make cash flow table for 10 years reflecting the total savings of switching from gas car to electric car

The government is offering an incentive of $11,000 for trading your gas car in and buying an electric vehicle

Assume that cost of gas will increase by 5% each year

You must include NPV and IRR for both comparisons in excel AND make a reccommendation

Interest rate = 4.50%

(you are free to make any other assumtions or rates you make, but be sure to clearly list them)

Imagine you are a pipeline company trying to sell a new project to a shipper of oil for a new refinery in Grand Forks. In order to prepare for selling this idea to shippers and hopefully win the contract, you need to calculate the average cost per unit ($/barrel) of oil to ship over this line in the first year; taking into account Capital, Operating and Energy Cost. This is a competitive proposal, so you will want to make sure your price is as low as you can make it!! The refinery is scheduled to take 300,000 barrels per day of Bakken Crude at typical temperures. Pipeline construction costs average $100,000/foot mile. A foot mile is 1 mile of 12 inch pipe. 2 miles of 16” pipe would be 2.6667 foot mile, and so on. The price includes all pipe and installation and is based on using X-42 and schedule 20 pipe. You have the option of increasing the pipe wall thickness to schedule 40 for an additional 10% and schedule 80 for 20% more than schedule 20. You also have the option of increasing the pipe strength to X60 for an additional 10% or X-72 for 20% above X-42. Each pump station will cost $2,000,000 +$2000/hp of pump. The inlet pressure of pumping stations should not fall below 400 psi. Pipeline flows entirely through class I locations except for 10 miles located in a class IV location. You have the option of bypassing the class IV location by running the pipeline an additional 50 miles. Cost of electricity to drive pumps is $.08 per kWh. (1 kW for 1 hour) Annualized Capital costs can be assumed to be an estimated by a fixed charge rate of .15 (meaning it costs 15% of the total project cost each year to cover debt and equity used to finance the construction) The fixed O&M is $0.10 per inch mile The variable O&M is $0.25 per barrel Hint: Partial credit will be awarded based on the following scale: Please note

1. Robert, a new client of yours, is a self-employed caterer in Santa Fe, New Mexico. Robert drives his personal van when delivering catered meals to customers. You have asked him to provide the amount of business miles driven using his vehicle. You are planning on using the standard mileage method to calculate Robert’s deduction for transportation costs. Robert has responded by saying, “Well, I don’t really keep track of my miles. I guess I drove around 3,000 miles last year for the business.” Please let us know how you would respond to Robert.
2. Your supervisor has asked you to research a potential tax deduction for a client, Nancy Fradette. Nancy is a seat-filler at a number of the award shows that are filmed in the greater Los Angeles area. Although typically seat-fillers are not compensated, Nancy is so good at the job that many of the events are willing to pay for her services. As a result, her level of seat-filling activity now rises to the level of a business, not just a hobby. In 2018, Nancy is hoping to take a trip to the National Award Show Association (NASA) Annual Conference being held in Koror, Palau, a small island country in the Pacific. Although the conference is specifically focused on the presentation of award shows, a large number of the producers of these shows attend each year. Nancy wanted to attend so she could understand the challenges an award show producer faces and thus better perform her seat-filler job. The conference is held in a remote location each year as award show producers generally prefer a high level of secrecy around the inner-workings of the shows, and the scuba-diving and weather are also pretty good. The costs to attend the conference are $1,200 for conference registration, $2,300 for air travel, $2,400 for lodging. All the meals are included in the cost of the registration and are valued at $400. Please prepare a letter to Nancy that describes the issues that Nancy will face in trying to deduct the cost of this trip. Use IRS Publication 463 (available at www.irs.gov (Links to an external site.)) to assist you.

Data We are interested in exploring the relationship between the weight of a vehicle and its fuel efficiency (gasoline mileage). The data in the table show the weights, in pounds, and fuel efficiency, measured in miles per gallon, for a sample of vehicles. Note the units here are pounds and miles per gallon.

1. Is the correlation significant? Explain how you determined this in complete sentences.
2. Is the relationship a positive one or a negative one? Explain how you can tell and what this means in terms of weight and fuel efficiency.
3. In one or two complete sentences, what is the practical interpretation of the slope of the least squares line in terms of fuel efficiency and weight?
4. For a car that weighs 4,000 pounds, predict its fuel efficiency. Include units.
5. Can we predict the fuel efficiency of a car that weighs 10,000 pounds using the least squares line? Explain why or why not.
6. Answer each question in complete sentences.
   1. Does the line seem to fit the data? Why or why not?
   2. What does the correlation imply about the relationship between fuel efficiency and weight of a car? Is this what you expected?
7. Are there any outliers? If so, which point is an outlier?

ProCannons Donuts: An alum of BSU, Donna Smith, knew the donuts baked by ProCannons donuts would sell like wildfire in the city where She was the new CEO of a local supermarket. They had 20 stores spaced out in the City of Farside Ohio, 200 miles away. The stores were on average 10 miles apart from the city center. Donna suggested that it would be easy to get the donuts to her stores; just buy a fleet of the Ram Sprinter vans at $50K each and have them deliver the needed 1000 lbs. of donuts a day each store would need. It would be all highway driving. You wondered if that was that the most economical logistics system to use for the long term. You did some research and found that instead of a fleet of Sprinter vans maybe a day hauler than cost $100K, and can haul 20,000 lbs. could take the donuts to a warehouse space where you could distribute each stores’ shipment to just two sprinters that went from the warehouse and back 10 times each day. Everyone on your logistics team makes $50,000 a year. You use a 250 day working year. The Day hauler truck must be back at the bakery at the end of the day so it cannot deliver to any of the stores there in Farside. Your company uses a 5 year cost payment scheme for rolling stock and 20 years for buildings. The Warehouse you would have to buy with your day hauler scheme would cost $5,000,000, and you would need 4 people to unload and load the trucks. The Per mile costs highway for the Sprinter would be .35 ( for the fleet of Sprinters going to each store) and .45 for in-town from the warehouse; the Day hauler per mile cost is 1.65. No vehicle would be allowed to drive more than 400 miles in a day. What is the total daily cost? Which option is the best economically? What are two different pieces of information that could change, or might be too simplistic in this scenario.

A.

Product Costs using Activity Rates

Atlas Enterprises Inc. manufactures elliptical exercise machines and treadmills. The products are produced in its Fabrication and Assembly production departments. In addition to production activities, several other activities are required to produce the two products. These activities and their associated activity rates are as follows:

The activity-base usage quantities and units produced for each product were as follows:

Use the activity rate and usage information to calculate the total activity cost and activity cost per unit for each product. If required, round the per unit answers to the nearest cent.

B.

High-Low Method for a Service Company

Boston Railroad decided to use the high-low method and operating data from the past six months to estimate the fixed and variable components of transportation costs. The activity base used by Boston Railroad is a measure of railroad operating activity, termed "gross-ton miles," which is the total number of tons multiplied by the miles moved.

Determine the variable cost per gross-ton mile and the total fixed cost.

How cold is it outside? The temperature alone is not enough to provide the answer. Other factors including wind speed, relative humidity, and sunshine play important roles in determining coldness outside. In 2001, the National Weather Service (NWS) implemented the new wind-chill temperature to measure the coldness using temperature and wind speed. The formula is:

t_wc = 35.74 + 0.6215t_a - 35.75v^0.16 + 0.4275t_av^0.16

t w c = 3.74 + 0.6215 t a − 35.75 v 0.16 + 0.4275 t a v 0.16

where t_a is the outside temperature measured in degrees Fahrenheit, v is the speed measured in miles per hour, and t_wc is the wind-chill temperature. The formula cannot be used for wind speeds below 2mph or temperatures below -58°F or above 41°F.

Write a program that prompts the user to enter a temperature between -58°F and 41°F and a wind speed greater than or equal to 2 then displays the wind-chill temperature. Use Math.pow(a, b) to compute v^0.16. Your class must be named Windchill. Here is a sample run:

Enter a temperature between -58°F and 41°F: 5.3
Enter the wind speed (>= 2) in miles per hour: 6
The wind chill index is -5.567068455881625

This is what I made:

import java.util.Scanner;
public class Windchill
{
public static void main(String[]args)
{
//create Scanner
Scanner s=new Scanner(System.in);
double ta= 5.3;
int v= 6;
double v2= Math.pow(v,.16);
double Windchill= 35.74 + 0.6215 * ta-35.75 * v2+0.4275 * ta * v2;
//get temperature in Fahrenheit
System.out.println("Enter a temperature between -58°F and 41°F:" +" "+ ta);
//get wind speed
System.out.println("Enter the wind speed (>= 2) in miles per hour"+" "+ v);
//get windchill index
System.out.println("The windchill index is"+" "+ Windchill);
}
}

My teacher told me: "your program needs to let the user enter the temperature and wind speed at the keyboard."

How do I fix this? please help.

Mini Case Study – Sales and Marketing at the Edgewater Hotel Seattle Set on the Pier 67 in the Seattle Central Waterfront, the Edgewater is one of the most iconic properties in all of the Pacific Northwest. The hotel first opened as a temporary building, meant to attract visitors for the 1962 World's Fair. Today has built a rich history to match its ideal location and luxurious furnishings, but there’s a growing debate among the Sales & Marketing team about the direction of its market positioning. Bob Peckenpaugh, General Manger of the property, needs your help in deciding on their strategy A History of Rock ‘n Roll The Edgewater became famous both inside and outside of Seattle for hosting some of the biggest names in music. During the height of the “British Invasion” of America, the Beatles helped put the Edgewater on the map. A few months after the Beatles famous set on the Ed Sullivan Show, the Beatles spent the third stop on their first tour of America at the (then named) Edgewater Inn. Seattle hotel owners were afraid of riots and damage from a visit, so Don Wright, then Manager of the property took them in as he knew they would get a lot of attention for the Edgewater Inn. He was right.

1. Who do you think are the customers of Edgewater today? Does that align with the product?

2. What approach option do you think that Bob should take? Why is that the right approach or why are the other options the wrong approach?
