Northwood and Eastwood are rival schools that wish to compare how their students did in a math competition. 72 randomly chosen Northwood students participated and received a mean score of 28 with a standard deviation of 8, 98 randomly chosen Eastwood students participated and received a mean score of 25 with a standard deviation of 10.
(a) The Eastwood math teacher wants to show through statistics that her students receive a higher mean score in the contest. State her hypotheses.
(b) Compute the test statistic and p-value for this test.
(c) Reach your conclusion at the 0.05 significance level. Be sure to interpret in the context of the problem
(d) In a separate test, the Eastwood teacher finds evidence that Eastwood students performed better than Southwood students. Would this prove that the Eastwood teacher was more effective than the Southwood teacher? Explain briefly.

New York wants to do a study to compare students at two
different schools in the city to see if student’s feelings about
college are influenced by their tuition. The city takes a sample of
100 students from Barnard college whose tuition is 60 thousand
dollars a year and 200 from Lehman College whose tuition is 15
thousand dollars a year. They ask each student the same question
“Do you feel that your college is worth the tuition you pay...

In an effort to compare student grades in 4 different high
schools, random samples of students from 4 local high schools were
selected. Their first year average college grades were computed and
recorded. Can we conclude that there are differences in the mean
grades of these students from those 4 high schools? (20

method to determine specifically whether schools A and C have a
significant difference in population means.

3. It is frequently difficult for graduate schools to compare
students from different undergraduate programs since universities
have vastly different scales of assessment. Some schools, for
example, are known to in ate grades while others maintain more
rigorous grading standards. Say that you are a graduate school
admissions officer charged with selecting those applicants that
have the best undergraduate grades relative to their peers. You
must decide between two students - one from Princeton and one from
Temple. The Princeton...

Two statistics professors at two rival schools decide to use IQ
scores as a measure of how smart the students at their respective
schools are. IQ scores are known to be Normally distributed. The
two professors will use this knowledge to their advantage. They
will randomly select 10 students from their respective schools and
determine the students' IQ scores by means of the standard IQ test.
