Universal Leasing leases electronic equipment to a variety of businesses. The company’s primary service is providing alternate financing by acquiring equipment and leasing it to customers under long-term sales-type leases. Universal earns interest under these arrangements at a 11% annual rate.
  
The company leased an electronic typesetting machine it purchased for $40,900 to a local publisher, Desktop Inc. on December 31, 2017. The lease contract specified annual payments of $8,959 beginning January 1, 2018, the beginning of the lease, and each December 31 through 2019 (three-year lease term). The publisher had the option to purchase the machine on December 30, 2020, the end of the lease term, for $22,700 when it was expected to have a residual value of $26,700, a sufficient difference that exercise seems reasonably certain. (FV of $1, PV of $1, FVA of $1, PVA of $1, FVAD of $1 and PVAD of $1) (Use appropriate factor(s) from the tables provided.)

Required:
1. Show how Universal calculated the $8,959 annual lease payments for this sales-type lease.
2. Prepare an amortization schedule that describes the pattern of interest revenue for Universal Leasing over the lease term.

Show how Universal calculated the $8,959 annual lease payments for this sales-type lease. (Round your intermediate and final answers to the nearest whole dollar amount.)

Prepare an amortization schedule that describes the pattern of interest revenue for Universal Leasing over the lease term. (Round your intermediate and final answers to the nearest whole dollar amount. Enter all amounts as positive values.)

Heart rates for newborns born in one of two hospitals were measured to determine whether birth outcomes are comparable at the two locations. Assume the hospitals are independent.

a) Test for a significant difference between mean heart rate in the two hospitals. Remember, as always, to give hypotheses, a p-value, and any other necessary information. Choose an appropriate p-value.

We compare the length of stay in days from several randomly selected patients:

a) Why is a t-test inappropriate in this case?

b) Conduct an appropriate nonparametric test to determine whether the two hospitals are com- parable in length of stay. Report a conclusion and necessary work.

PURPOSE

The purpose of this assignment is to develop learners’ ability to analyse data and discuss the differences between the types of statistics.

Cordova, Inc., reported the following receivables in its December 31, 2017, year-end balance sheet:

Additional information:

The notes receivable account consists of two notes, a $120,000 note and a $290,000 note. The $120,000 note is dated October 31, 2017, with principal and interest payable on October 31, 2018. The $290,000 note is dated March 31, 2017, with principal and 10% interest payable on March 31, 2018. Interest rate on $120,000 note is 6%

During 2018, sales revenue totaled $2,110,000, $1,970,000 cash was collected from customers, and $40,000 in accounts receivable were written off. All sales are made on a credit basis. Bad debt expense is recorded at year-end by adjusting the allowance account to an amount equal to 10% of year-end gross accounts receivable.

Required:
1. In addition to sales revenue, what revenue and expense amounts related to receivables will appear in Cordova’s 2018 income statement?
2. Calculate the receivables turnover ratio for 2018. (Round your answer to 2 decimal places.)

Interest Revenue

Bad Debt Expense

AR Turnover Rate?

Scammers Inc. has developed a new Immune Booster drink (IB) as well as a “cure” for Covid-19 based on Colloidal Silver (CS). As the product manager for the firm, you are responsible for setting the pricing policy for the new products. You are considering a bundled package that includes both products, and you assume the marginal cost of production is zero for planning purposes. You have identified four basic types of customers who may buy these new products, and their reservation prices for the two new products are provided in the following table:

1. Suppose you sell the two products separately, and each buyer is expected to purchase one unit of the product per week. Which prices for IB and CS maximize weekly revenue? What is the weekly revenue equal to?

2. If you offer the two products under a pure bundling strategy, what is the revenue maximizing bundle price? What is the weekly sales revenue from the pure bundling scheme?

3. What are your firm’s profits if you charge $19 for a bundle containing one unit of IB and one unit of CS but also sell the products separately at a price of $14 for IB and $18 for CS?

6.      Hernandez Tool and Die has three service? departments:

Cost-allocation bases are budgeted as? follows:

1.      Supposed Hernandez allocates all service department costs directly to the production departments without allocation to other service departments. How much of the budgeted costs of each service department are allocated to each production department? Choose the most logical cost-allocation base for each service department. To plan your work, examine number 2 before undertaking this question.

2.      The company has decided to use the step-down method of cost allocation. General factory administration would be allocated first, then cafeteria, then engineering. Cafeteria employees work 43,400 labor hours per year. There were 60 engineering employees with 356,600 total labor hours. Recompute the results in number 1, using the step-down method. Show your computations. Compare the results in numbers 1 and 2. Which method of allocation is best? Why?

3.      For each type of cost assignment made in number 2 using the step-down method, indicate the assignment type.
