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.
