Pelican Stores

Pelican Stores, a division of National Clothing, is a chain of women’s apparel stores operating throughout the country. The chain recently ran a promotion in which discount coupons were sent to customers of other National Clothing stores. data collected for a sample of 100 in-store credit card transactions at Pelican Stores during one day while the promotion was running are contained in the file named PelicanStores. Table 2.19 shows a portion of the data set. The Proprietary Card method of payment refers to charges made using a National Clothing charge card. Customers who made a purchase using a discount coupon are referred to as promotional customers and customers who made a purchase but did not use a discount coupon are referred to as regular customers. because the promo- tional coupons were not sent to regular Pelican Stores customers, management considers the sales made to people presenting the promotional coupons as sales it would not other- wise make. Of course, Pelican also hopes that the promotional customers will continue to shop at its stores.

Most of the variables shown in Table 2.19 are self-explanatory, but two of the variables require some clarification.

- Items The total number of items purchased

- Net Sales The total amount ($) charged to the credit card

Pelican’s management would like to use this sample data to learn about its customer base and to evaluate the promotion involving discount coupons.

Managerial Report

Use the tabular and graphical methods of descriptive statistics to help management develop a customer profile and to evaluate the promotional campaign. At a minimum, your report should include the following:

1. Percent frequency distribution for key variables.

2. A bar chart or pie chart showing the number of customer purchases attributable to the method of payment.

3. A crosstabulation of type of customer (regular or promotional) versus net sales. Comment on any similarities or differences present.

4. A scatter diagram to explore the relationship between net sales and customer age.

Table 2.19

a. Production & Cost Relationship in the Long-Run

b.

(4 pts) Comment on the shape of the short-run total production curve that gives the input and output relationship in the short-run. Sketch and explain the shape. Your answer should be specific to the information given in the table above.

An electronics store has 4 branches in a large city. They are curious if sales in any particular department are different depending on location. They take a random sample of purchases throughout the 4 branches – the results are recorded below. Run an independence test for the data below at the 0.05 level of significance.

What is the Test statistic (?2) and how is it done in excel?

You are considering an investment with the following cash flows. Your required return is 8%, you require a payback of 3 years and a discounted payback of 4 years. If your objective is to maximize your wealth, should you take this investment?

Cash Flow –$50,000 $20,000 $20,000 $20,000 $20,000 –$50,000

Hearne Company has a number of potential capital investments. Because these projects vary in nature, initial investment, and time horizon, management is finding it difficult to compare them. Assume straight line depreciation method is used. (Future Value of $1, Present Value of $1, Future Value Annuity of $1, Present Value Annuity of $1.) (Use appropriate factor(s) from the tables provided.)

Project 1: Retooling Manufacturing Facility
This project would require an initial investment of $4,910,000. It would generate $919,000 in additional net cash flow each year. The new machinery has a useful life of eight years and a salvage value of $1,860,000.

Project 2: Purchase Patent for New Product
The patent would cost $3,610,000, which would be fully amortized over five years. Production of this product would generate $559,550 additional annual net income for Hearne.

Project 3: Purchase a New Fleet of Delivery Trucks
Hearne could purchase 25 new delivery trucks at a cost of $137,800 each. The fleet would have a useful life of 10 years, and each truck would have a salvage value of $5,600. Purchasing the fleet would allow Hearne to expand its customer territory resulting in $233,000 of additional net income per year.

Required:
1. Determine each project's accounting rate of return.
2. Determine each project's payback period.
3. Using a discount rate of 10 percent, calculate the net present value of each project.
4. Determine the profitability index of each project and prioritize the projects for Hearne.

Determine each project's accounting rate of return. (Round your answers to 2 decimal places.)

Determine each project's payback period. (Round your answers to 2 decimal places.)

Using a discount rate of 10 percent, calculate the net present value of each project. (Round your intermediate calculations to 4 decimal places and final answers to 2 decimal places.)

Determine the profitability index of each project and prioritize the projects for Hearne. (Round your intermediate calculations to 2 decimal places. Round your final answers to 4 decimal places.)

Lili, a great magician, has a mission to enter a cave to get treasure inside. The cave only
has 1 path without branches. But the cave is not safe because there are some traps inside
that can reduce Lili’s life points. But in addition to traps, the cave also has potions that
can increase Lili’s life points. Before entering the cave, Lili casts magic that can reveal all
the traps and potions inside the cave. But before entering the cave, Lili must prepare her
life points first because in the cave because Lili cannot use her magic to add life points
or destroy the traps. What is the minimum life point that Lili must prepare so that her
life point is always positive during the trip inside the cave.
Note: If Lili’s point drops to 0 or negative before entering and during the trip inside the
cave, then Lili is declared dead.
Format Input
There are
T test cases. Each testcase contains an integer
N which represents the length
of the cave. On the next line there are
N numbers represents the value of trap and potion.
Traps are marked with numbers that are negative and potions are marked with numbers
that are positive
Format Output
Output
T line with format “Case
#
X: ”, where
X represents the testcase number and
Y represents the initial life points that Lili has to prepare.

Sample Input (standard input) 25
1 2 -3 4 -5 5
-1 -1 -1 -2 9
Sample Output (standard output)
Case #1: 2
Case #2: 6
Explanation
In case 1, the minimum life points that Lili must prepare is 2. With a simulation like the
following.
At position 1, Lili’s life point increased by 1 to 3.
At position 2, Lili’s life point increased by 2 to 5.
At position 3, Lili’s life point is reduced by 3 to 2.
At position 4, Lili’s life point increased to 4 to 6.
At position 5, Lili’s life point is reduced by 5 to 1.
In each position Lili’s life points are positive so the answer is valid. if the initial life
prepared by Lili is 1, then Lili will die in fifth position with a life point of 0.

Please answer it in C language , thx

Factor the following:

a) f(x)=x^5+5x^4-21x^3-137x^2-88x+240, knowing that f(5)=0 and f(-3)=0.

b) f(x)=x^3+8x^2+5x-50

c)f(x)=-x^4-4x^3+19x^2+46x-120, knowing that (x+5) and (x-2) are factors.
