The Dean of the Business School at State University would like to test the hypothesis that no difference exists between the average final exam grades for the Introduction to Marketing course and the Introduction to Finance course. A random sample of eight students who took both courses was selected and their final exam grades for each course are shown below. Student 1 2 3 4 5 6 7 8 Marketing 82 86 74 93 90 76 87 100 Finance 76 91 70 79 96 70 85 81 If Population 1 is defined as the Marketing exam scores and Population 2 is defined as the Finance exam scores, and using LaTeX: \alpha α = 0.05, the conclusion for this hypothesis test would be that because the test statistic is _______________________________________________________. less than the critical value, we can conclude that no difference exists between the average final exam grades for the Introduction to Marketing course and the Introduction to Finance course less than the critical value, we cannot conclude that a difference exists between the average final exam grades for the Introduction to Marketing course and the Introduction to Finance course more than the critical value, we cannot conclude that a difference exists between the average final exam grades for the Introduction to Marketing course and the Introduction to Finance course more than the critical value, we can conclude that a difference exists between the average final exam grades for the Introduction to Marketing course and the Introduction to Finance course

The dean of the college of business at one of the state
university systems believes that the college rankings are
positively correlated to the private endowments ($1,000,000) and
the annual budgets ($1,000,000) from state and private sources. To
support his claim, the dean collects the following data from nine
of the state’s peer institutions and the rankings of each
school:
Private Endowment

Annual Budget

Dean Parmalee wished to know if the year-end grades assigned to
Wright State University Medical School students are predictive of
their second-year medical board scores. The following table shows,

A dean of a business school wanted to know whether the graduates
of her school used the statistic skills that they learn in
university during their first year of employment after graduation.
As of today there are 34,050 graduates in total from the business
school. The Dean is committed to allocate more funding to the
development of the school’s statistics course if at least 17% of
its graduates use statistics skills during their first year of
employment. She surveyed 500...

The dean of the College of Business at the University of La
Verne has observed for several years and found that the probability
distribution of the salary of the alumni’s first job after
graduation is normal. The college collected information from 121
alumni and finds that the mean of their salary is $60k. Assuming a
95% confidence level, please do the following
1. Suppose the dean believes that the average salary of the
population should be about $58k per year,...

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
Ha:μ<3.6
H0:p=3.64/4
Ha:p≠3.64/4
H0:p=3.6/4
Ha:p>3.6/4
H0:p=3.6/4

H0:μ=3.6

H0:μ=3.6
Ha:μ≠3.6
