You are given the sample mean and the population standard deviation. Use this information to construct the​ 90% and​ 95% confidence intervals for the population mean. Interpret the results and compare the widths of the confidence intervals. If​ convenient, use technology to construct the confidence intervals.

A random sample of 55 home theater systems has a mean price of ​$136.00. Assume the population standard deviation is ​$18.60.

a) The​ 90% confidence interval is ​____

b) The​ 95% confidence interval is ____

c) Interpret the results. Choose the correct answer below.

a.

With​ 90% confidence, it can be said that the population mean price lies in the first interval. With​ 95% confidence, it can be said that the population mean price lies in the second interval. The​ 95% confidence interval is wider than the​ 90%.

b.

With​ 90% confidence, it can be said that the sample mean price lies in the first interval. With​ 95% confidence, it can be said that the sample mean price lies in the second interval. The​ 95% confidence interval is wider than the​ 90%.

c.

With​ 90% confidence, it can be said that the population mean price lies in the first interval. With​ 95% confidence, it can be said that the population mean price lies in the second interval. The​ 95% confidence interval is narrower than the​ 90%.

Java- Fill in the blanks

Print numbers 0, 1, 2, ..., userNum as shown, with each number indented by that number of spaces. For each printed line, print the leading spaces, then the number, and then a newline. Hint: Use i and j as loop variables (initialize i and j explicitly). Note: Avoid any other spaces like spaces after the printed number. Ex: userNum = 3 prints:

0
 1
  2
   3

--------------------------------------------

public class NestedLoop {
public static void main (String [] args) {
int userNum = 0;
int i = 0;
int j = 0;

/* Your solution goes here */

return;
}
}

Given numRows and numCols, print a list of all seats in a theater. Rows are numbered, columns lettered, as in 1A or 3E. Print a space after each seat, including after the last. Use separate print statements to print the row and column. Ex: numRows = 2 and numCols = 3 prints:

1A 1B 1C 2A 2B 2C 

-----------------------------------------------------------

public class NestedLoops {
public static void main (String [] args) {
int numRows = 2;
int numCols = 3;

// Note: You'll need to declare more variables

/* Your solution goes here */

System.out.println("");

return;
}
}

For each of the following anecdotes, briefly explain (i) why the described is potentially inconsistent with standard economic theory and (ii) why it is potentially consistent with a behavioral theory we learned in this course.

(a) Some students who were about to buy a ticket to a campus theater group were randomly selected and given a discount. Those who were given the discount were much more likely to buy a ticket for a second showing.

(b) The AARP recently asked a series of prominent lawyers to provide services for retirees at a highly discounted rate of $30 an hour. Very few lawyers agreed to do so. Then, the AARP simply asked the lawyers to volunteer their time for free to help the same retirees. At that point, many lawyers agreed to help out

(c) A bank offers two types of savings accounts, called Gold and Silver. The two types of accounts give the same rate of return, but the Silver account does not allow you to withdraw any money for six months. The bank manager is surprised when many people sign up for the Silver account.

(d) Cab drivers in New York City work longer hours on warm, sunny days (when their per-hour wage is low).

Scenario 1 - Ethical Dilemma - Reclassify Employees

You are on the management team of Crystal Clear Electronics (CCE) Inc., a company that specializes in high-quality home theater systems. In addition to selling these systems, CCE provides custom installation on all purchases and is known for the professionalism of its installation staff. This reputation is due to the rigorous policies its home installation staff must follow. All employees are required to attend bi-monthly training sessions, wear CCE uniforms, observe the installation dates and times agreed on by CCE and the customer, and follow any instructions given by CCE as to how to perform the installation.

Faced with shrinking margins and cash flow problems, CCE is looking to cut costs and increase cash flows. You realize that by reclassifying the installation staff as independent contractors, CCE will be able to accomplish both objectives. Because the installation staff would be independent contractors, the company would not have to pay payroll taxes, social security, and Medicare expenses. The reduction in these costs and the corresponding increase in cash flow would certainly help the company's liquidity. Furthermore, such a change would not affect the quality of the service provided and would be virtually invisible to customers.

Question: Discuss the ethical implications of this reclassification.

Weighted Average Cost Method with Perpetual Inventory

The beginning inventory at Midnight Supplies and data on purchases and sales for a three-month period ending March 31, 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 5, using the weighted average cost method. Round unit cost to two decimal places, if necessary.

2. Determine the total sales, the total cost of merchandise sold, and the gross profit from sales for the period.

1. Meow Supplies applies manufacturing overhead costs to products at a budgeted indirect-cost rate of P60 per direct manufacturing labor-hour. A retail outlet has requested a bid on a special order of the Toy Mouse product. Estimates for this order include: Direct materials P40,000; 500 direct manufacturing labor-hours at P20 per hour; and a 20% markup rate on total manufacturing costs.
