Ethan is an orderly in a skilled nursing care facility. He is charged  with supervising patients in the dining room on a day when  two of his coworkers have called in sick, leaving  the facility shorthanded. On this day, several patients seem more irritable than usual, and  Ethan is kept busy  preventing outbursts and calming them. He also worries about  patients prone  to choking episodes, and finds himself feeling harried and stressed.

Wallace, an 80-year-old confined to a wheelchair, demands that Ethan help him back to his room. "It's a mad­ house in here today,"  he shouts. Ethan  knows  he cannot  leave his post,  and panics when Wallace heads for the door.

Ethan runs ahead  of Wallace, shuts the double doors to the dining room, and locks them.

1. Has Ethan acted ethically?  Explain  your answer.
2. What would you do in a similar situation?  Use steps one through five for ethical decision  making to reach a solution. Describe how each step was used.
3. Do you believe your solution is more ethical  than Ethan's? Why or why not?

THIS IS NOT MEANT TO BE A SAMPLE TEST. EXAM QUESTIONS MAY NOT BE SIMILAR TO THOSE IN THIS REVIEW.

1. Read the values of the variable VOL in the dataset IQandBrainSize and find the proportion of sample values within 1, 2 and 3 sample standard deviations from the mean.

2. Nucryst Pharmaceutical, Inc. announced the results of its first human trial of NPI 32101, a topical form of its skin ointment. A total of 225 patients diagnosed with skin irritations were randomly divided into three groups as part of a double-blind, placebo-controlled study to test the effectiveness of the new topical cream. The first group received a 0.5% cream, the second group received a 1.0% cream, and the third group received a placebo. Groups were treated twice daily for a 6-week period.

Solve EXACTLY 6 questions out of 10. At least 2 questions MUST be quantitative! "X" = 7, "Y" = 4:

1. QUANTITATIVE – You work for Lynn, Inc. Your boss has asked you to complete a forecast for February and March using two forecasting methods and then to evaluate the two methods to identify the “best” method. You decide to try a weighted moving average of the last two months using weights of 60% (previous month) and 40% (2 months prior). You also try exponential smoothing with an alpha constant of .34.  Complete the table by providing numbers for A, B, C, D, E, F, G, and H and calculate the MAD for each method (I and J). Which is a better forecasting method for this data? Why?

Substitute the last digit of your student number for “Y”=7. Substitute the next to last digit of your student number for "X"=4.

MAD for Weighted Average = I

MAD for Exponential Smoothing = J

Write a program that asks the user for a number of seconds and tells them how
many hours, minutes and seconds it is. Make sure your program works correctly
for values smaller than the whole hour or whole minute. Here’s what the sample
output from several runs of your program would look like:
Please enter the number of seconds: 2
