Question

Juniors in Valley West high school are assigned to 2 math teachers at random. Simple random
samples of 50 juniors from each class were followed for 5 years. Out of the 50 juniors in Ms.
Wellman's class, 28% majored in a STEM field, 42% majored in a different field, and 30% did not
go to a 4-year college. Out of the 50 juniors in Mr. Parker's class, 42% majored in a STEM field, 28%
majored in a different field, and 30% did not go to a 4-year college.

and use the table in the book to calculate the p-value. Be sure to state the null hypothesis.
