A bank with a branch located in a commercial district of a city has the business objective of improving the process for serving customers during the noon-to-1 pm lunch period. To do so, the waiting time (defined as the number of minutes that elapses from when the customer enters the line until he or she reaches the teller window) needs to be shortened to increase customer satisfaction. A random sample of 15 customers is selected and the waiting times are recorded. Suppose that another branch, located in a residential area, is also concerned with the noon-to-1 pm lunch period. A random sample of 15 customers is selected and the waiting times are recorded. Data are available in the worksheet labeled “Problem 3”.

4. Conduct an appropriate test to compare the mean waiting times of the two branches. Report the p-value of this test and state your conclusions.

For each of the following independent situations, answer the specific revenue concerns (provide authoritative support where appropriate). Use new revenue recognition, ASC 606.

1)        Company A enters into a contract on February 1, 2018 to manage rental property for Company B for the next 5 years. Company A will provide all services related to the management of the property and will receive a monthly payment equal to 2% of the gross rentals from the property. Historically, property of this type in this area has averaged an 85% occupancy rate. How should Company A determine the amount and timing of revenue recognition under this contract?

2)        Company A is constructing a high-rise luxury apartment building. The building will contain 80 apartments of similar size and layout. During 2018, Company A receives a deposit of $100,000 from a customer for one of the apartments. The deposit is only refundable if Company A fails to complete the building. Company A expects completion early in 2019. The remainder of the apartment’s sale price ($900,000) is due from the customer at the completion of the building when the customer can take possession. Can Company A recognize revenue in 2018 related to the contract with the customer paying the deposit?

3)        Bakery A has an incentive plan that gives its customers one point for each doughnut purchased. A customer that has accumulated 15 points can receive a free doughnut. During the current year, Bakery A sold 201,600 doughnuts at $1.20 each. Bakery A expects 90% of the points to be redeemed and 10,500 were redeemed in the current year. How much revenue should Bakery A recognize in the current year related to the sale of the doughnuts and the incentive plan?
