Data from the Framingham Study allow us to compare the distributions of initial serum cholesterol levels for two populations of males: those who go on to develop coronary heart disease and those who do not. The mean serum cholesterol level of the population of men who do not develop heart disease is µ = 206mg/10ml and the standard deviation is σ = 36mg/100ml. Suppose, however, that you do not know the true population mean; instead, you hypothesize that µ is equal to 230mg/100ml. This is the mean initial serum cholesterol level of men who eventually develop the disease. Since it is believed that the mean serum cholesterol level for the men who do not develop heart disease cannot be higher than the mean level for men who do, a one-sided test conducted at the α = 0.05 level of significance is appropriate.

a. How could you increase the power?

b. You wish to test the null hypothesis H0: µ ≥ 230mg/100ml against the alternative HA: µ < 230mg/100ml at the alpha = 0.05 level of significance. If the true population mean is as low as 206mg/100ml, you want to risk only a 5% chance of failing to reject H0. How large a sample would be required?

c. How would the sample size change if you were willing to risk a 10% chance of failing to reject a false null hypothesis?

Pitman Company is a small editorial services company owned and operated by Jan Pitman. On October 31, 2019, the end of the current year, Pitman Company's accounting clerk prepared the following unadjusted trial balance:

The data needed to determine year-end adjustments are as follows:

Required:

• Unexpired insurance at October 31, $4,560.
• Supplies on hand at October 31, $560.
• Depreciation of building for the year, $3,010.
• Depreciation of equipment for the year, $2,610.
• Unearned rent at October 31, $1,690.
• Accrued salaries and wages at October 31, $2,950.
• Fees earned but unbilled on October 31, $17,300.

1. Journalize the adjusting entries using the following additional accounts: Salaries and Wages Payable; Rent Revenue; Insurance Expense; Depreciation Expense—Building; Depreciation Expense—Equipment; and Supplies Expense.

Feedback

1. Before you begin, identify which adjusting entry goes with which additional account. As you go through each of these, consider the other sides of the adjusting entry transaction and identify related accounts. Keep in mind that you will be making an adjusting entry for each of these that affects at least one income statement account (revenues or expenses) and one balance sheet account (assets or liabilities). In the case of the insurance transaction, you will have to calculate the amount of insurance expired. In the case of supplies, you will need to calculate the amount of supplies used (expense). In the case of rent, you will need to calculate the amount of rent earned (revenue).

1. Journalize the adjusting entries using the following additional accounts, Salaries and Wages Payable, Rent Revenue, Insurance Expense, Depreciation Expense—Building, Depreciation Expense—Equipment, and Supplies Expense.

Identify possible challenge stressors and the hindrance stressors that could be affecting your team members. Is it possible for the same stressor to be a challenge stressor to one person and a hindrance stressor to another? Explain your answer, please.

Please answer questions in the order listed. You do not need to be completely correct, but I do need to see an honest effort. For this post, YOU MUST SHOW YOUR WORK, on any question requiring math. This is to make it so that I can see where exactly where you mis-stepped in your calculation or logic, and/or so that your classmates can learn from you.

Lab 9: Phone Call

Write a program that will calculate the cost of a phone call as follows:

1. The first 10 minutes are charged at a flat rate of $0.99 (Not 99 cents a minute - but 99 cents for the first 10 minutes or less).
2. This means that a phone call of 1 minute or 6 minutes or 10 minutes will be charged the same flat rate of 99 cents.
3. Every minute after the initial 10 minutes will be charged at $0.10 per minute.
4. Input the number of minutes talked as an integer.
5. Using an IF/ELSE structure, check for an entry of 0 minutes first, and inform the User that no minutes were entered.
   
   • IF 0 minutes are entered THEN
     • output an error message stating that no minutes were entered.
   • ELSE
     • Calculate and display the results.
     • The final display will show the minutes and the final cost.
     • The price will be formatted with 2 decimal places.
   • END IF

Include all Prologue information with your program

• Include an Initial Algorithm

Middler Corporation, a manufacturer of electronics and communications systems, uses a service department charge system to charge profit centers with Computing and Communications Services (CCS) service department costs. The following table identifies an abbreviated list of service categories and activity bases used by the CCS department. The table also includes some assumed cost and activity base quantity information for each service for October. CCS Service Category Activity Base Budgeted Cost Budgeted Activity Base Quantity Help desk Number of calls $96,750 2,500 Network center Number of devices monitored 660,250 9,500 Electronic mail Number of user accounts 71,000 7,100 Handheld technology support Number of handheld devices issued 142,400 8,900 One of the profit centers for Middler Corporation is the Communication Systems (COMM) sector. Assume the following information for the COMM sector: The sector has 2,000 employees, of whom 60% are office employees. Almost all office employees (90%) have a computer on the network. 95 percent of the employees with a computer also have an e-mail account. The average number of help desk calls for October was 1 calls per individual with a computer. There are 290 additional printers, servers, and peripherals on the network beyond the personal computers. All the nonoffice employees have been issued a handheld device. a. Determine the service charge rate for the four CCS service categories for October. Round your answers to two decimal places. CCS Service Category Service Charge Rate Help desk $ Per call Network center $ Per device monitored Electronic mail $ Per user or e-mail account Handheld technology support $ Per device b. Determine the charges to the COMM sector for the four CCS service categories for October.
