The table for Exercise 6.80 at the bottom of the page describes (approximately) the distribution of students by gender and college at a mid-sized public university in the West. If we were to randomly select one student from this university:
a. What is the probability that the selected student is a male?
b. What is the probability that the selected student is in the College of Agriculture?
c. What is the probability that the selected student is a male in the College of Agriculture?
d. What is the probability that the selected student is a male who is not from the College of Agriculture?
Support your contention with three examples from your experience at other organizations or departments. Where applicable, for each example, indicate what are the treatments and blocking variables.
At the .01 significance level can we conclude the mean age is more than 8.4 years for the cars of university students? State the null hypothesis and the alternate hypothesis.
