Math 533 Part C Essay

A company computes its accounts receivable turnover to be 20. Based on this information, find the average collection period. If the company has a credit collection period of 30 days, explain the relationship between the credit collection period and the average collection period. Average collection period is 18.25. The relationship between the credit collection period and the average collection period is very good for this company. This company will receive payments owed to them prior to them having to pay whom they owe.

2. Use the graph below to predict what the results will look like if the null hypothesis is rejected. The total arousal counts in the control treatment at each interval is graphed for you. Justify your predictions.

Build an Excel spreadsheet to estimate how much a prospective customer is worth, depending on whether that customer is offered a rebate. What do you learn from the updated spreadsheet? Explain the logic behind your findings and

| What is the efficiency of your line balance? (Round your answer to 2 decimal places. Omit the "%" sign in your response.)

The mean for the column “mean” is 3.56. It is very close to the parameter of interest but is not equal to it. You can calculate a confidence interval for the mean of the mean column, but a specific confidence interval would need to be provided. In that case, the confidence interval would be centered on 3.56, not 3.5.

95%=(4264, 5086)- I am 95% confident that the average credit balance for suburban customers falls between $4264 and $5,086.

Is this estimate centered about the parameter of interest (the parameter of interest is the answer for the mean in question 2)?

AJ DAVIS is a department store chain, which has many credit customers and wants to find out more information about these customers. A sample of 50 credit customers is selected with data collected on the following five variables:

4) Use cubic regression to determine an equation for the data (or lwh where (12 – x) represents the sides and (x) represents the height of the box).

The average number of breakdowns from the simulation trials was 1.93 with a standard deviation of 0.20. No. of breakdowns per week

Problem 2.4: Consider the sample from a bank database shown in Figure 2.14; it was selected randomly from a larger database to be the training set. Personal Loan indicates whether a solicitation for a personal loan was accepted and is the response variable. A campaign is planned for a similar solicitation in the future, and the bank is looking for a model that will identify likely responders. Examine the data carefully and indicate what your next step would be.

c.)Find a 95% confidence interval for the difference between the above obtained mean starting salaries.

How many repair records should be sampled if the research firm wants the population mean number of miles driven until transmission failure to be estimated with the margin of error of 5000 miles? Use 95% confidence.

d) If Tyler is estimating a gross profit margin, or contribution margin, of 40 percent, how much of the receivables balance must actually

The line of best-fit is used to find the gradient, the T2/L value, if straight or linear it shows that the relationship between the two is directly proportional. Using the original equation, you can square both sides and rearrange it to make . Then you can input the gradient value (T2/L) and work out g. , where g equals 10.13 m/s2. This value is close to the
