Suppose a young couple deposits $600 at the end of each quarter in an account that earns 6.8%, compounded quarterly, for a period of 2 years. After the 2 years, they start a family and find they can contribute only $200 per quarter. If they leave the money from the first 2 years in the account and continue to contribute $200 at the end of each quarter for the next 18 1/2 years, how much will they have in the account (to help with their child's college expenses)? (Round your answer to the nearest cent.)

Two factories located in different cities, owned by the same organization (ABC Corp), produce the identical product. The product they make is a specialized all-terrain vehicle. In 2002, based on productivity data from a random sample of workers, management felt the average labor productivity of the two plants could be improved. So, both plants underwent identical process improvements through 2003. In 2004, the worker productivity was gauged for both plants using the same set of workers.

Factory A Before = worker productivity for Factory A measured in units finished per day measured in 2002 i.e. before improvement intervention

Factory B Before = worker productivity for Factory B measured in units finished per day measured in 2002 i.e. before improvement intervention

Factory A After = worker productivity for Factory A measured in units finished per day measured in 2004 i.e. after improvement intervention

Factory B After = worker productivity for Factory B measured in units finished per day measured in 2004 i.e. after improvement intervention

You are the consultant and the management wants the following questions answered.

1. Was there a difference in average worker productivity between factories A and B before the process improvement began?
2. Do the two factories (A and B) differ in terms of average productivity after the process improvement?
3. Did the process improvement intervention help improve the average worker productivity in ABC Corp?
4. Did the process improvement intervention help improve the average worker productivity in factory A?
5. Did the process improvement intervention help improve the average worker productivity in factory B?
6. Did the average worker productivity in Factory A improve more than the average worker productivity in Factory B?

Assume α-level of 10%. You have to use p value method. Assume equal variances wherever needed.

Bird’s data analyst wants to model the sample mean and sample variance of net revenue of scooters. They plan to take a random sample of 25 of its scooters in Austin. They will record weekly net revenue brought in by each scooter. They decide it is reasonable to assume that weekly revenue of scooters is approximately normally distributed with a standard deviation of $50 (variance of 2,500 squared dollars).
Find values a and b such that (i) the probability is 0.9 that the sample standard deviation s will be between a and b and (ii) the probability is 0.05 that s will be less than a. What is the value of a? what is the value for b?

A home exercise machine is marketed in three ways: via e-mail, by sending a DVD to prospective customers who access the manufacturer’s website, and via telemarketing. For each marketing approach records are kept regarding how many prospective customers make a purchase. The results are summarized as follows:

(a) Do the sample data provide evidence that the proportion of customers who decided to make a purchase is different for different marketing approaches? Set up and perform an appropriate test at the ? = 0.05 level of significance.
(b) If your conclusion in Part (a) was to reject the null hypothesis (and it should be!) then use the Marasculio procedure to determine which proportions are different for which other proportions. Again, use ? = 0.05.

Waiting times​ (in minutes) of customers at a bank where all customers enter a single waiting line and a bank where customers wait in individual lines at three different teller windows are listed below. Find the coefficient of variation for each of the two sets of​ data, then compare the variation. Bank A​ (single line): 6.6 nbsp 6.6 nbsp 6.7 nbsp 6.8 nbsp 7.0 nbsp 7.3 nbsp 7.5 nbsp 7.7 nbsp 7.7 nbsp 7.8

Bank B​ (individual lines): 4.4 nbsp 5.4 nbsp 5.7 nbsp 6.2 nbsp 6.8 nbsp 7.6 nbsp 7.8 nbsp 8.6 nbsp 9.2 nbsp 9.7

The coefficient of variation for the waiting times at Bank A is

b. find coefficient of variance for vaiting times in Bank B: %

Well, both leading and lagging indicators can be related to economic (financial) and non-economic (non-financial) factors.

For example, in my question above about measuring customer satisfaction, the number of projects or orders delivered on time or within the budget would leading indicators of customer satisfaction, whereas the customer satisfaction index and repeat customers would be lagging indicators of it.

So, suppose you have been asked to help a restaurant that is really struggling with its dining room experience, food choices, kitchen management, and overall profitability. Profit is declining because weekly sales are declining. Getting new customers and retaining existing customers has been an issue. What are some non-financial performance measures that you will recommend in building a balanced scorecard (in all three non-financial areas of it) for this business

Ms. Cold would like to have a number of tests in place for candidates to answer as part of the selection process. She would also like to measure the work performance of the servers within the first ninety-days of employment. You were assigned to develop the following tests:

Compose a situational judgment test for servers of the restaurant. The test should include:

Four multiple choice questions of possible situations waiters/servers may encounter when dealing with customers.

Four possible answer choices for each question.

On a separate sheet, indicate the rating scale for each question.

Prepare a BES Rating Dimension for the servers. The rating dimension should cover three scales:

Interactions with customers;

Server’s responsiveness and attitude with customers; and

The server’s demeanor when taking orders.

Yerbury Corp. manufactures construction equipment.

Journalize the entries to record the following selected equity investment transactions completed by Yerbury during a recent year:

In your computations, round per share amounts to two decimal places. When required, round final answers to the nearest dollar. For a compound transaction, if an amount box does not require an entry, leave it blank.
