The following are some “suspicions”; you have been requested to select some effective extended procedures designed to confirm or deny the suspicions. Required: Write the suggested procedures for each case in definite terms so another person can know what to do. a. The custodian of the petty cash fund may be removing cash on Friday afternoon to pay for weekend activities. b. A manager noticed that eight new vendors were added to the purchasing department’s approved vendor list after the assistant purchasing agent was promoted to chief agent three weeks ago. She suspects all or some of them might be fictitious companies set up by the new chief purchasing agent. c. The payroll supervisor may be stealing unclaimed paychecks of employees who resigned and did not collect their last check. d. Although no customers have complained, cash collections on accounts receivable have decreased and the counter clerks may have stolen customers’ payments. e. The cashier may have “borrowed” cash receipts, covering this by holding each day’s deposit until cash from the next day(s) collection is enough to make up the shortage from an earlier day and then sends the deposit to the bank

Researchers gave 40 index cards to a waitress at an Italian restaurant in New Jersey. Before delivering the bill to each customer, the waitress randomly selected a card and wrote on the bill the same message that was printed on the index card. Twenty of the cards had the message "The weather is supposed to be really good tomorrow. I hope you enjoy the day!" Another 20 cards contained the message "The weather is supposed to be not so good tomorrow. I hope you enjoy the day anyway!" After the customers left, the waitress recorded the amount of the tip (percent of bill) before taxes. Here are the tips for those receiving the good-weather message:

21.2   19.1   20.3   20.6   22.4   23.5   23.3   25.2   22.6   20.3

24.9   22.3   27.0   20.9   22.6   24.4   21.6   22.4   22.3   23.2

The tips for the 20 customers who received the bad-weather message are listed here:

18.0   19.3   19.4   19.1   18.4   19.5   18.7   16.3   16.8   14.3

17.0   14.1   17.8   20.2   20.7   19.2   18.0   23.3   18.7   19.8

The experiment data in below table was to evaluate the effects of three variables on invoice errors for a company. Invoice errors had been a major contributor to lengthening the time that customers took to pay their invoices and increasing the accounts receivables for a major chemical company. It was conjectured that the errors might be due to the size of the customer (larger customers have more complex orders), the customer location (foreign orders are more complicated), and the type of product. A subset of the data is summarized in the following Table.

Table: Invoice Experiment Error

Customer Size: Small (-), Large (+)

Customer Location: Foreign (-), Domestic (+)

Product Type: Commodity (-), Specialty (=)

Reference: Moen, Nolan, and Provost (R. D. Moen, T. W. Nolan and L. P. Provost. Improving Quality through Planned Experimentation. New York: McGraw-Hill, 1991)

Use the date in table above and answer the following questions in the space provided below:

1. What is the nature of the effects of the factors studied in this experiment?
2. What strategy would you use to reduce invoice errors, given the results of this experiment?

PC.52 At the start of the semester Custom Kicks personnel were struggling to quickly customize their shoe inserts to their customers' feet. This hurt sales as customers became frustrated during the customization process and would hesitate to refer friends. During week three of running the business, it took an average employee about 20 minutes to customize one pair of inserts. Recognizing this challenge, management and key employees analyzed the customization process and made some time-saving changes. Two weeks later, after training all employees on the new process, an average employee could customize a pair of inserts in about 14 minutes. In this case, what is the output that should be used for productivity calculations? 1 pair (of customized inserts) 20 minutes 14 minutes After making the time-saving changes mentioned above, how many pair of inserts could an average employee complete in one hour? (Display your answer to two decimal places.) After making the time-saving changes mentioned above, by what percentage did Custom Kicks' productivity increase? (Write your answer as a percentage, and display your answer to two decimal places.) %

Maynard Company projects the following sales for the first three months of the year: $15800 in January; $15,900 in February; $11,100 in March. The company expects 60% of the sales to be cash and the remainder on account. Sales on account are collected 50% in the month of the sale and 50% in the following month. The Accounts Receivable account has a zero balance on January 1. Round to the nearest dollar.

Requirements:

2.) Prepare a revised schedule of cash receipts if receipts from sales on account are 70% in the month of the sale, 10% in the month following the sale, and 20% in the second month following the sale. What is the balance in Accounts Receivable on March 31?
