Suppose that we randomly select 50 billing statements from each of the computer databases of the Hotel A, the Hotel B, and the Hotel C chains, and record the nightly room rates. The means and standard deviations for the data are given in the table.

(a) Find a 95% confidence interval for the difference in the average room rates for the Hotel A and the Hotel B chains. (Use Hotel A − Hotel B. Round your answers to two decimal places.)

$______ to $______

(b)Find a 99% confidence interval for the difference in the average room rates for the Hotel B and the Hotel C chains. (Use Hotel B − Hotel C. Round your answers to two decimal places.)

$______ to $______

A stock's returns have the following distribution:

The survey by The Bureau of Labor Statistics American Time, showed that the time a person spends in the United States using a computer for entertainment varies greatly according to age. Individuals aged 75 years and older averaged 0.3 hrs (18 minutes) per day. Those aged 15 to 19 spent 1.0 hrs a day. If these times follow an exponential distribution find the proportion of each group that passes:
a) Less than 15 minutes a day using the computer to
entertainment
b) More than two hours
c) Between 30 and 90 minutes

Internal Control Case Study

Harper Theater is located in Midtown Mall. The cashier’s booth is near the entrance to the theater. Two cashiers are employed. Once works from 1-5 pm, the other from 5-9 pm.   Each cashier is bonded. The cashiers receive cash from customers and operate a machine that ejects serially numbered tickets. The rolls of tickets are inserted and locked into the machine by the theater manager at the beginning of each cashier’s shift.

After purchasing a ticket, the customer takes the ticket to an usher stationed at the entrance to the theater lobby some 60 feet from the cashier’s booth. The usher tears the ticket in half, admits the customer, and returns the ticket stub to the customer. The other half of the ticket is dropped into a locked box by the usher.

At the end of each cashier’s shift, the theater manager removes the ticket roll from the machine and makes a cash count. The cash count sheet is initialed by the cashier. At the end of the day, the manager deposits the receipts in total in a bank night deposit vault located in the mall. The manager also sends copies of the deposit slip and the initialed cash count sheets to the theater company treasurer for verification and to the company’s accounting department. Receipts from the first shift are stored in a safe located in the manager’s office.

Required: using Microsoft Word, answer the following questions and attach the document to this assignment:

1. Identify the internal control procedures and their application to the cash receipts transactions of the Harper Theater. You will find the Internal Control Procedures (Proper documentation, Adequate insurance, Separation of assets from custody, Separation of duties, and Use of technology). For each Internal Control Procedure, identify any Internal Control Procedures that Harper Theater has in place and/or is missing. Be specific and use at least 300 words for your answer.
2. If the usher and cashier decide to collaborate to misappropriate cash, what actions might they take? For each action, what internal control might be employed to stop the misappropriation of cash? Be specific and use at least 200 words for your answer.
