1. Determine the effect size in the following research example and state whether it is a small, medium, or large effect size:

Population 1: Mean = 307, SD = 22

Population 2: Mean = 300, SD = 22

2. Conduct the appropriate type of t-test (one-sample or paired samples) for the following example: Florida Atlantic University feels that their medical school is significantly better than other programs throughout the country. The 20 medical students who graduated from FAU in 2019 were given a performance exam before their residency programs began. The average score in the class was a 95 percent with a sum of squares of 1500. The nationwide average on this exam is a 92 percent.

2A. What is the estimated standard deviation based on the sample?

2B. What is the t-statistic and cutoff score (.05 test, 2-tailed) in the t-distribution

2C. Is there evidence to support the hypothesis that FAU's program better prepares its students than other programs (is the test significant) ?

3. As a further measure for the effectiveness of the medical program, FAU decides to administer the same exam to five students in their first year, and then again when they graduate the program: Use the scores below to conduct a t-test and determine whether the scores significantly change over time.

First Year Graduation

85 88

88 93

82 86

92 95

91 96

3B. State the t-statistic and cutoff score (.05-test, 2-tailed) in the t-distribution

3C. Was the test significant?
