Part A. SPSS Assignment
In this exercise, you are playing the role of a researcher that is testing new medication designed to improve cholesterol levels. When examining cholesterol in clinical settings, we look at two numbers: low-density lipoprotein (LDL) and high-density lipoprotein (HDL). You may
have heard these called “good” (HDL) and “bad” (LDL) cholesterol. For LDL, lower numbers are better (below 100 is considered optimal).For HDL, 60 or higher is optimal.

In this experiment, you will be testing three different versions of the new medication. In data file “Activity 8.sav” you will find the following variables: group (0=control, 1=Drug A, 2=Drug B, 3=Drug C), LDL, and HDL (cholesterol numbers of participants after 12 weeks).

4. Why is a 99% confidence interval wider than a 95% confidence interval?

12. A person claims to be able to predict the outcome of flipping a coin. This person is correct 16/25 times. Compute the 95% confidence interval on the proportion of times this person can predict coin flips correctly. What Conclusion can you draw about this test of his ability to predict the future?

15. You take a sample of 22 from a population of test scores, and the mean of your sample is 60. (a) You know the standard deviation of the population is 10. What is the 99% confidence interval on the population mean. (b) Now assume that you do not know the population standard deviation, but the standard deviation in your sample is 10. What is the 99% confidence interval on the mean now?

1. True or False. Justify for full credit. (25 pts) (a) The volume of milk in a jug of milk is 128 oz. The value 128 is from a discrete data set. (b) If the variance from a data set is zero, then all the observations in this data set must be zero. (c) P(A ANDA ) 0, whereA is the complement of A. c c (d) The mean and median for a normal distribution are always the same. (e) In a hypothesis testing, if the p-value is less than the significance level α, we do not have sufficient evidence to reject the null hypothesis. Refer to the following frequency distribution for Questions 2, 3, 4, and 5. Show all work. Just the answer, without supporting work, will receive no credit. A random sample of 25 customers was chosen in UMUC MiniMart between 3:00 and 4:00 PM on a Friday afternoon. The frequency distribution below shows the distribution for checkout time (in minutes). Checkout Time (in minutes) Frequency Relative Frequency 1.0 – 1.9 6 2.0 – 2.9 8 3.0 – 3.9 4.0 – 5.9 5 Total 25 2. Complete the frequency table with frequency and relative frequency. (5 pts) 3. What percentage of the checkout times was less than 3 minutes? (5 pts) 4. In what class interval must the median lie? Explain your answer. (5 pts) 5. Assume that the largest observation in this dataset is 5.8. Suppose this observation were incorrectly recorded as 8.5 instead of 5.8. Will the mean increase, decrease, or remain the same? Will the median increase, decrease or remain the same? Why? (5 pts)

Week 7 Assignment: Analyze Samples, Power Analysis, and Design Sensitivity in \$25 Only

Activity Description
Submit the Following
1. Calculate the sample size needed given these factors:
one-tailed t-test with two independent groups of equal size small effect size (see Piasta, S.B., & Justice, L.M., 2010)
alpha =.05
beta = .2
Assume that the result is a sample size beyond what you can obtain. Use the compromise function to compute alpha and beta for a sample half the size. Indicate the resulting alpha and beta. Present an argument that your study is worth doing with the smaller sample.
