I need to determine if men have higher health care costs then women for 1 year. Both groups have 500 people all between the age of 20-40 collected from 10 hospitals and this data was collected from 50 random men and 50 random women. The annual expenses must be added and recorded. I need to post the data that was used to figure the data in excel formatting. The calculation of test statistic and p value is to be calculated and the two tailed p value done as well. I need to show the graph related to the z statistic and the rejection with critical values. Then inference: What is the decision rule. I am lost, and need help determining this. Thank you.

An air transport association surveys business travelers to develop quality ratings for transatlantic gateway airports. The maximum possible rating is 10. Suppose a simple random sample of 50 business travelers is selected and each traveler is asked to provide a rating for a certain airport. The ratings obtained from the sample of 50 business travelers follow.

6 4 6 8 7 6 6 3 3 7 10 4 8 7 8 7 5 9 4 8 4 3 8 5 4 4 4 4 8 3 5 7 2 5 9 9 8 4 8 9 9 4 9 7 8 3 10 7 9 6

Develop a 95% confidence interval estimate of the population mean rating for this airport. (Round your answers to two decimal places.)

Java Script.

Develop a program that will determine the slugging percentages and batting average of several New York Yankees from the 2006 season. Slugging percentage is calculated by dividing the total number of bases by the number of at bats. The number of bases would be one for every single, two for every double, three for every triple, and four for every home run. The batting average is calculated by dividing the total number of hits by the number of at bats. You do not know the number of players in advance, but for each player you know their number of singles, doubles, triples, home runs, total number of at bats, and the player's name (use the proper type and method for each variable).

You will use a while sentinel loop on the 1st item to input. If it is not the sentinel, go into the while sentinel loop and separately input the rest of the input items (be careful of the enter in the input memory buffer for the player name). You will then calculate the total bases and the slugging percentage. You will then calculate the batting average. You will then print out the player's name, the labeled slugging percentage for that player to three decimal places, and the labeled batting average for that player to three decimal places. Use separate output statements. Print a blank line between players. This loop will repeat for as many players as you need.

Run your program with the following players and sentinel value (to show the sentinel value worked):

Create a java script. Modify your program that determined the slugging percentages and batting average of several New York Yankees from the 2006 season. The user now knows in advance the number of players to process. You will ask the user to input the number of players and input that value into a variable. You will use a while loop to check their input. While their input is less than zero or more than twenty, you will ask them to re-input the number of players, since the number of players has to be from zero to twenty. Use proper form for the while loop. Since we now know the number of players, use a for loop to count up to their number. Inside the loop, input all the data, calculate the batting average and slugging percentages, and print the name, batting average, and slugging percentage as in the while sentinel loop. Use proper form for the for loop. Make sure everything from part one is working properly. Slugging percentage is calculated by dividing the total number of bases by the number of at bats. The number of bases would be one for every single, two for every double, three for every triple, and four for every home run. The batting average is calculated by dividing the total number of hits by the number of at bats. You do not know the number of players in advance, but for each player you know their number of singles, doubles, triples, home runs, total number of at bats, and the player's name (use the proper type and method for each variable). Then use a for loop with a counter. While the counter is less than or equal to the number of players, go into the for loop and separately input the items (be careful of the enter in the input memory buffer for the player name). You will then calculate the total bases and the slugging percentage. You will then calculate the batting average. You will then print out the player's name, the labeled slugging percentage for that player to three decimal places, and the labeled batting average for that player to three decimal places. Use separate output statements. Print a blank line between players. This loop will repeat for as many players as the user asked for. Run your program with the following input and players: Enter number of players (0 – 20): 25 Invalid number of players. Enter number of players (0 – 20): -1 Invalid number of players. Enter number of players (0 – 20): 3 Singles: 158 Doubles: 39 Triples: 3 Home Runs: 14 At Bats: 623 Player: Derek Jeter Singles: 51 Doubles: 25 Triples: 0 Home Runs: 37 At Bats: 446 Player: Jason Giambi Singles: 104 Doubles: 26 Triples: 1 Home Runs: 35 At Bats: 572 Player: Alex Rodriguez

McCormick & Company is considering a project that requires an initial investment of $24 million to build a new plant and purchase equipment. The investment will be depreciated as a modified accelerated cost recovery system (MACRS) seven-year class asset. The new plant will be built on some of the company's land, which has a current, after-tax market value of $4.3 million. The company will produce bulk units at a cost of $130 each and will sell them for $420 each. There are annual fixed costs of $500,000. Unit sales are expected to be $150,000 each year for the next six years, at which time the project will be abandoned. At that time, the plant and equipment is expected to be worth $8 million (before tax) and the land is expected to be worth $5.4 million (after tax).To supplement the production process, the company will need to purchase $1 million worth of inventory. That inventory will be depleted during the final year of the project. The company has $100 million of debt outstanding with a yield to maturity of 8 percent, and has $150 million of equity outstanding with a beta of 0.9. The expected market return is 13 percent, and the risk-free rate is 5 percent. The company's marginal tax rate is 40 percent.

Questions Below

5. What is the total operating cash flows, given the following operating cash flows:

Sales = 150,000 x $420 = $63,000,000

Costs = 150,000 x $130 + $500,000 = $20,000,000

6. Create an after-tax cash flow timeline.

7. What are the total expected cash flows at the end of year six? The $4.3 million is an opportunity cost and must be included at date zero as a cash outflow. If the project is accepted, however, the land can be sold in six years for $5.4 million.
