Assumption:

1. The acquisition cost for each new customer is $35.

2. Each customer will purchase five times a year. For each purchase, the profit value is $8.

3. Retention rate (r) is 80% and Interest rate (i) is 4.5%.

Questions:

Note: Please round up all answers to the nearest tenth (two digits after the decimal point).

(1) Please fill out the empty cells in the table below. And write down all the detailed calculation steps.

(2) In order to make profit from this program, how many years do you think that the customers should stay in this program? Please simply explain why.

(3) Assuming that the retail store can attract 350 customers after it launches the frequent shopper program, and be able to keep this amount of customers till the end of year 4. The owner plans to achieve $3,000 cumulative profits at the end of year 4. Do you think, with 350 frequent shoppers, can the store owner accomplish the $3,000 goal? If not, how many more customers the retail store should recruit and keep till the end of year 4?

Write the basic feasible solution from the tableau given.

Lab 1 Data

Suppose that 30% of all homeowners in an earthquake-prone area of California are insured against earthquake damage. Four homeowners are selected at random; let x denote the number among the four who have earthquake insurance.

(a) Find the probability distribution of x. (Hint: Let S denote a homeowner who has insurance and F one who does not. Then one possible outcome is SFSS, with probability (.3)(.7)(.3)(.3) and associated x value of 3. There are 15 other outcomes.)

(b) What is the most likely value of x?

b) what is the slope of the line in this plot equal to ( not a number)

c) determine the slope of the graph by determing the least Squares best fit line to the data. what is "g" determined from slope?

A housewife is testing the cutting speeds of 4 brands of knives she has at home. She chose 5 cutting materials of varying degree at home. Each material was cut once by each one of the 4 knives. (Hence after all 4 cuts the material was cut into 5 pieces).
1) Is this a randomized block design or two factor design?
If random block design, what is used as the block?
If two factor design, what are the two factors in the study?
1. State the null and alternative hypotheses.

Depreciation by Three Methods; Partial Years

Perdue Company purchased equipment on April 1 for $77,760. The equipment was expected to have a useful life of three years, or 7,560 operating hours, and a residual value of $2,160. The equipment was used for 1,400 hours during Year 1, 2,600 hours in Year 2, 2,300 hours in Year 3, and 1,260 hours in Year 4.

Required:

Determine the amount of depreciation expense for the years ended December 31, Year 1, Year 2, Year 3, and Year 4, by (a) the straight-line method, (b) units-of-output method, and (c) the double-declining-balance method.

Note: FOR DECLINING BALANCE ONLY, round the multiplier to four decimal places. Then round the answer for each year to the nearest whole dollar.

Present/future value computations

1. How much must be deposited on January 1, 2013 to accumulate a balance of $50,000 on December 31, 2017? At interest rate of 3.5%
At interest rate of 6%
2. 50,000 is deposited at interest compounded annually what amount will be on hand in seven years at 4%? at 8%
2A. What if 50,000 is deposited at interest compounded semi-annually what amount will be on hand in seven years At 4%? At 8%
3. How much must be deposited at 4.5% interest on January 2, 2019 to pay an annuity of 1,000 per year on December 31 of each year for six years?
3A. What would the amount be if the annuity was paid on January 1 instead of December 21?
4. How much would be on hand if 1,000 were deposited annually at 4.5% for six years?

The corporate CEO of "Life is Fun and Love is Strange Inc." claimed that the average sales of "Fun Life" are less than "Strange Love". In order to test the hypothesis, she asked you to conduct 2 tests. a) test the claim that the variances of the 2 stores are equal. Use a 5% significance level. b) based on your answer, use the appropriate test for the claim that the average sales of "Strange Love" are greater than "Fun Life". Use a 5% significance level for the test.
