The high temperatures for three different cities were recorded over the course of several days, and the data is below.
City A: 90, 89, 88, 95, 92, 90, 91
City B: 86, 85, 90, 90, 89, 96, 89
City C: 88, 84, 86, 82, 86, 82, 83
Determine if there are were any significant differences in mean high temperature between the three cities. Use a 5% significance level for the initial ANOVA and a corrected alpha for any post hoc tests if needed.

Since we are attempting to examine the behavior of a class of
students, the behavior of an individual (as we calculated in
objective 1) is really of little concern to us. Assuming that there
are 30 students enrolled for a typical class, use the central limit
theorem to calculate the following:
• What would be the shape of the
distribution of the average class grade of these 30 students?
• What would be the average class

answer
A department chair wanted to know if students gained knowledge
during completion of a Masters program. All 8 of the
students were given a pre test prior to beginning the program, and
then given the post test after completing the last course.
Select the correct statistical test; perform the test; report
the results according to the handbook guidelines; explain what the
results mean to the professor.
