# Question

Is there evidence consistent with gender discrimination in training level? To answer this, proceed as follows:

a. Create a table of counts for the two qualitative variables “gender” and “training level.”

b. Compute the overall percentage table and comment briefly.

c. Compute a table of percentages by gender; then comment.

d. Compute a table of percentages by training level; then comment.

e. Is it appropriate to use the chi-squared test for independence on this data set? Why or why not?

f. Omit training level C, restricting attention only to those employees at training levels A and B for the rest of this exercise. Compute the expected table.

g. Still omitting training level C, compute the chi-squared statistic.

h. Still omitting training level C, report the results of the chi-squared test for independence at the 5% level. Comment on these results.
