1)
Annual sales (=demand), D = 4000 sets
Order cost, S = $ 25
Holding cost, H = $ 5
Current order quantity, Q = D/2 = 4000/2 = 2000 sets
Optimal order quantity, EOQ = sqrt(2DS/H)
= sqrt(2*4000*25/5)
= 200 sets
Annual holding cost of current policy = H*Q/2
= 5*2000/2
= $ 5000
Annual holding cost of optimal policy = H*EOQ/2
= 5*200/2
= $ 500
Difference in holding costs = 5000 - 500
= $ 4,500

A firm’s corporate strategy is driven largely by its top management team. One method of gauging the influence of marketing on corporate strategy is to measure the proportion of firms with a chief marketing officer on their top management team. Over the 5-year period from 2000 to 2004, 42% of firms had a chief marketing officer on their top management team. [Source: Pravin Nath and Vijay Mahajan, “Chief Marketing Officers: A Study of Their Presence in Firms’ Top Management Teams,” Journal of Marketing, 70 (2007).] To test the hypothesis that the influence of marketing on corporate strategy today is different from its influence in the 2000–2004 period, a random sample of 91 U.S. firms is selected. Of these, 26 firms have a chief marketing officer on their top management team. The test is conducted at a significance level of α = 0.01. Let p be the true proportion of firms with a chief marketing officer currently on their top management team.
To conduct the hypothesis test, the null and alternative hypotheses are formulated as: A. H₀: p ≥ 0.42; Ha: p < 0.42 B. H₀: p̄ = 0.42'; Ha: p̄ ≠ 0.42 C. H₀: p = 0.42; Ha: p ≠ 0.42 D. H₀: p ≤ 0.42; Ha: p > 0.42 If the null hypothesis is true, the sampling distribution of the sample proportion p̄ can be approximated by ____ with a mean of ____ and a standard deviation of ___ . The test statistic is ____. Use the Distributions tool to develop the rejection region. According to the critical value approach (with α = 0.01), when do you reject the null hypothesis? Reject H₀ if t ≤ –2.632 or if t ≥ 2.632 Reject H₀ if z ≤ –2.576 Reject H₀ if z ≤ –2.576 or if z ≥ 2.576 Reject H₀ if z ≤ –2.326 or if z ≥ 2.326 Use the provided Distributions tool to determine the p-value. The p-value is ____. Using the critical value approach, the null hypothesis is (not rejected/rejected), because ___. Using the p value approach, the null hypothesis is (not rejected/rejected), because ____. Therefor you (can/cannot) conclude that the influence of marketing on corporate strategy today is different from its influence in the 2000–2004 period.

Bloomington Publishers is considering publishing five different textbooks. The maximum number of copies of each textbook that can be sold, the variable cost of producing each textbook, the sales price of each textbook, and the fixed cost of a production run for each textbook are given in the file Prob3. For example, producing and selling 2000 copies of book 1 yields a revenue of $80(2000) = $160,000 but costs $80,000 + $44(2000) = $168,000. This company can produce at most 20,000 copies in total. Furthermore, it can publish no more than three different types of textbooks. Also, it knows that it cannot publish book 1 if it chooses to publish book 2. Finally, if this company publishes book 4 it must also publish book 5. Bloomington Publishers wants to find a production plan that maximizes total profit. Formulate and solve an integer programming model in Prob3 to help this publisher identify the best production plan.

23. Savings Account Balance
Write a program that calculates the balance of a savings account at
the end of a three-
month period. It should ask the user for the starting balance and
the annual interest
rate. A loop should then iterate once for every month in the
period, performing the
following steps:
A) Ask the user for the total amount deposited into the account
during that month
and add it to the balance. Do not accept negative numbers.
B) Ask the user for the total amount withdrawn from the account
during that
month and subtract it from the balance. Do not accept negative
numbers or
numbers greater than the balance after the deposits for the month
have been
added in.
C) Calculate the interest for that month. The monthly interest rate
is the annual
interest rate divided by 12. Multiply the monthly interest rate by
the average of
that month’s starting and ending balance to get the interest amount
for the
month. This amount should be added to the balance.
After the last iteration, the program should display a report that
includes the following
information:
• starting balance at the beginning of the three-month period
• total deposits made during the three months
• total withdrawals made during the three months
• total interest posted to the account during the three
months
• final balance
test case:

Royal Ltd. manufactures equipment that is sold or leased. On 31 December 2017 Royal leased equipment to Water Ltd. for a non-cancelable lease term of three years ending 31 December 2020 at which time possession of leased asset will revert back to Royal Ltd.
The equipment cost $300,000 to manufacture and has an expected useful life of six years. Its normal sales price (fair value) is $365,760. The residual value was guaranteed by Water Ltd. for $10,000 at the end of lease term. Water Ltd. estimated the fair value of the equipment at end of lease term will be around $5,000.
Under the lease, three equal annual payments of $130,960 are due on December 31 of each year. The first payment was made on 31 December 2017. Water Ltd.’s incremental borrowing rate is 12%. Water knows the interest rate implicit in the lease payment is 10%. Both companies use straight-line depreciation and have the fiscal year ended at 31 December of each year. (Please use the discount table provided in your calculation, no decimal points in rounding, for example, 130.7 should be written as 131.)
Required:
1. The present value of the minimum lease payment (PVMLP) is _____.
2. Prepare the appropriate entries for Water Ltd. on 31 December 2017 & 2018. Indicate the date for each entry. Narratives for journal entries are not required.
3. Prepare the appropriate entries for Royal Ltd. on 31 December 2017. Narratives for journal entries are not required.
4. Prepare appropriate entries for Water Ltd. on 31 December 2020. Indicate the date for each entry. Narratives for journal entries are not required.
