Collecting Averages of Groups of Five Repeat steps one through five (of the section titled Collect the Data) with one exception. Instead of recording the change of 30 classmates, record the average change of 30 groups of five. 1. Randomly survey 30groups of fiveclassmates. 2. Record the values of the average of their change.

One hundred teachers attended a seminar on mathematical problem solving. The attitudes of representative sample of 12 of the teachers were measured before and after the seminar. A positive number for change in attitude indicates that a teacher's attitude toward math became more positive. The twelve change scores are as follows.

4; 7; −1; 1; 0; 5; −2; 2; −1; 6; 5; −3

1. What is the mean change score? (Round your answer to two decimal places.)

2. What is the standard deviation for this sample? (Round your answer to two decimal places.)

3. What is the median change score? (Round your answer to one decimal place.)

4. Find the change score that is 2.2 standard deviations below the mean. (Round your answer to one decimal place.)

FIFO Perpetual Inventory

The beginning inventory at Dunne Co. and data on purchases and sales for a three-month period ending June 30 are as follows:

Required:

1. Record the inventory, purchases, and cost of merchandise sold data in a perpetual inventory record similar to the one illustrated in Exhibit 3, using the first-in, first-out method. Under FIFO, if units are in inventory at two different costs, enter the units with the LOWER unit cost first in the Cost of Goods Sold Unit Cost column and in the Inventory Unit Cost column.

-- Determine the total sales and the total cost of goods sold for the period. Journalize the entries in the sales and cost of goods sold accounts. Assume that all sales were on account.

-- Determine the gross profit from sales for the period.
$______

-- Determine the ending inventory cost as of June 30.
$____________

-- Based upon the preceding data, would you expect the ending inventory using the last-in, first-out method to be higher or lower?

You have been asked by an investor to value a restaurant using discounted cash flow valuation. For the current year, the restaurant earned pretax operating income of $750,000. Income has grown 2% annually during the last five years, and is expected to continue growing at that rate for the next two years. Net operating working capital increased by $60,000 during the current year and current year capital spending on long-lived assets exceeded depreciation by $75,000. Both working capital and the excess of capital spending over depreciation are projected to grow at the same rate as operating income. Subsequent to the second year, you believe the pretax operating income growth rate will increase to 3% per year and remain at that level into the foreseeable future. The 10-year Treasury bond rate is 2.5%, the equity risk premium is 5.5%, and the marginal federal, state, and local tax rate is 35%. The restaurant’s beta and its target debt-to-equity ratio are 1.74 and 0.67, respectively. Its pretax cost of borrowing, based on its recent borrowing activities, is 9%. (Show Work)

What is the restaurant’s enterprise free cash flow in year 1?

A)$352,500 B)$420,750 C)$427,500 D)$359,550 E)$436,050

What is the restaurant’s enterprise free cash flow in year 2?

A)$370,337 B)$359,550 C)$436,050 D)$366,741 E)$388,745

What is the restaurant’s cost of equity?

A)14.5% B)12.07% C)7.72% D)7.72% E)9.13%

What are the restaurant’s target capital structure weights?

Dr. Lillian​ Fok, a New Orleans​ psychologist, specializes in treating patients who are agoraphobic​ (i.e., afraid to leave their​ homes). The following table indicates how many patients Dr. Fok has seen each year for the past 10 years. It also indicates what the robbery rate was in New Orleans during the same​ year.                                                                                                                                          

The simple linear regression equation that shows the best relationship between the number of patients and year is ​(round your responses to three decimal​ places):

ModifyingAbove y with carety ​=??????​+??????x where

ModifyingAbove y with carety ​= Dependent Variable and x​ = Independent Variable.

Using linear regression​, the number of patients Dr. Fok will see in year 11​=????? patients​ (round your response to two decimal​ places).

Using linear regression​, the number of patients Dr. Fok will see in year 12​=???? patients ​(round your response to two decimal​ places).

The coefficient of determination for the linear regression model is 0.8621 This shows that there is a (strong) OR (not so strong) relationship between the​ "Number of​ Patients" and​ "Year."

There are two parts to this activity. Before you write a Java program for this activity, write the pseudocode for this program. Turn in the pseudo code and Java program.

Create a program that prompts the user for an integer number. The program returns the factorial of the number. 0! = 1

In your program, answer the following question: What kind of loop are you using for this example? Counter-controlled loop or sentinel controlled loop? Explain.

Sample Input
Enter a number: 8

Sample Output
8! = 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 = 40320

Sample Input
Enter a number: 3

Sample Output
3! = 3 * 2 * 1 = 6

Sample Input
Enter a number: 10

Sample Output
10! = 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 = 3628800

Sample Input
Enter a number: 0

Sample Output
0! = 1 

Sample Input
Enter a number: 5

Sample Output
5! = 5 * 4 * 3 * 2 * 1 = 120

What was the age distribution of nurses in Great Britain at the time of Florence Nightingale? Suppose we have the following information. Note: In 1851 there were 25,466 nurses in Great Britain. a) Find the probability that a British nurse selected at random in 1851 would be 60 years of age or older. (Round your answer to three decimal places.)____________
b)Compute the expected age μ of a British nurse contemporary to Florence Nightingale. (Round your answer to two decimal places.)___________

c) Compute the standard deviation σ for ages of nurses shown in the distribution. (Round your answer to two decimal places.)___________

Edgerron Company is able to produce two products, G and B, with the same machine in its factory. The following information is available. Product G Product B Selling price per unit $ 50 $ 80 Variable costs per unit 10 48 Contribution margin per unit $ 40 $ 32 Machine hours to produce 1 unit 0.4 hours 1.0 hours Maximum unit sales per month 600 units 200 units The company presently operates the machine for a single eight-hour shift for 22 working days each month. Management is thinking about operating the machine for two shifts, which will increase its productivity by another eight hours per day for 22 days per month. This change would require $4,000 additional fixed costs per month. (Round hours per unit answers to 1 decimal place. Enter operating losses, if any, as negative values.)
