At a Midwestern business school, historical data indicates that 70% of admitted MBA students ultimately join the business school’s MBA program. In a certain year, the MBA program at the University admitted 200 students.
a. Find the probability that at least 150 students ultimately join the MBA program.
b. Find the probability that no less than 135 and no more than 160 students finally join the MBA program.
c. How many students should the MBA program expect to join the program?
d. What is the standard deviation of the number of students who will join the MBA program? e. Let X be the number of students out of 200 who will join the program. Would the empirical rule apply to the probability distribution of X in this case?

The Dean of ASBE School of Business is concerned that grades in
the MBA program are distributed appropriately. Too many high grades
or too many low grades would pose a problem. We wish to test the
claim that the mean GPA of ASBE students is smaller than 3.6 at the
.01 significance level.
The null and alternative hypothesis would be:
H0:μ=3.6

A business students claims that on average an MBA students is
required to prepare more than five cases per week. To examine the
claim, a statistics professor ask a random sample of ten MBA
students to report the number of cases they prepare weekly. The
results are given below. Can the professor conclude that the claim
is true, at the .05 level of significance, assuming the number of
cases is normally distributed with a standard deviation of 1.5?

Marilyn is a 23-year-old M.B.A. student at the business school
of a large Midwestern university. For years she has been frustrated
and dissatisfied with her life. She has always done well
academically, but lately she has had little interest in doing her
schoolwork and little confidence that she can do it well. She
describes herself as a person with "big plans," who ultimately
won't "cut it." She also fears that she will never be satisfied

A total of 23 Gossett High School students were admitted to
State University. Of those students, 7 were offered athletic
scholarships. The school’s guidance counselor looked at each
group’s summary statistics of their composite ACT scores, wondering
if there was a difference between the groups (those who were not
offered scholarships and those who were). The statistics for the 16
students who were not offered scholarships are x̅ = 24.7, s = 2.8
and for the 7 who were, x̅...
