Write sentences interpreting the academic track difference between the means of grades in high school and also visualization.

Respond to the following short answer questions from Chapter
4 in the Morgan, Leech, Gloeckner, & Barrett textbook:

D7.9.1 Under what conditions would you use a one-sample t
test? (b) Provide another possible example of its use from the HSB data.
D7.9.2 In Output 9.2: (a) Are the variances equal or
significantly different for the three dependent variables? (b) List the
appropriate t, df, and p (significance level) for each t test as you would in
an article. (c) Which t tests are statistically significant? (d) Write
sentences interpreting the academic track difference between the means of
grades in high school and also visualization. (e) Interpret the 95% confidence
interval for these two variables. (f) Comment on the effect sizes.
D7.9.3 (a) Compare the results of Outputs 9.2 and 9.3. (b)
When would you use the Mann–Whitney U test?
D7.9.4 In Output 9.4: (a) What does the paired samples
correlation for mother’s and father’s education mean? (b) Interpret/explain the
results for the t test. (c) Explain how the correlation and the t test differ
in what information they provide. (d) Describe the results if the r was .90 and
the t was zero. (e) What if r was zero and t was 5.0?

D7.9.5 (a) Compare the results of Output 9.4 with Output
9.5. (b) When would you use the Wilcoxon test?
