Question

Is there a difference between community college statistics students and university statistics students in what technology they use on their homework? Of the randomly selected community college students 43 used a computer, 72 used a calculator with built in statistics functions, and 65 used a table from the textbook. Of the randomly selected university students 28 used a computer, 33 used a calculator with built in statistics functions, and 40 used a table from the textbook. Conduct the appropriate hypothesis test using a 0.05 level of significance.

H_{0}: The distribution of the technology that community
college statistics students use for their homework is the same as
the distribution of the technology that university statistics
students use for their homework.

H_{1}: The distribution of the technology
that community college statistics students use for their homework
is not the same as the distribution of the technology that
university statistics students use for their homework.

p-Value = ["0.47", "0.73", "0.04", "0.008"]

**Conclusion:**

["There is insufficient evidence to conclude that the distribution of technology use for statistics homework is not the same for statistics students at community colleges and at universities."

["There is insufficient evidence to conclude that the distribution of technology use for statistics homework is not the same for statistics students at community colleges and at universities."]

We conduct a study to determine whether the majority of
community college students plan to vote in the next presidential
election. We choose a significance level of 0.05. We survey 650
randomly selected community college students and find that 54% of
them plan to vote. The P-value is 0.02.
H0: 50% of community college students plan to vote in
the next presidential election.
Ha: More than 50% of community college students plan
to vote in the next presidential election....

Cars on Campus. Statistics students at a community college
wonder whether the cars belonging to students are, on average,
older than the cars belonging to faculty. They select a random
sample of 37 cars in the student parking lot and find the average
age to be 8.5 years with a standard deviation of 6 years. A random
sample of 32 cars in the faculty parking lot have an average age of
5.1 years with a standard deviation of 4.1 years....

The college board claims that 32% of community college students
take five semesters to complete a two-year program. In a survey of
1400 randomly selected community college students enrolled in a
two-year program, 401 of them took five semesters to complete their
two-year program. Test the college board's claim at a level of
significance of 0.01.
Calculate the test statistics associated with this
hypothesis.

15% of all college students volunteer their time. Is the
percentage of college students who are volunteers larger for
students receiving financial aid? Of the 354 randomly selected
students who receive financial aid, 60 of them volunteered their
time. What can be concluded at the α = 0.10 level of significance?
For this study, we should use The null and alternative hypotheses

Do students at various universities differ in how sociable they
are? Twenty-five students were randomly selected from each of three
universities in a region and were asked to report on the amount of
time they spent socializing each day with other students. The
result for University X was a mean of 7 hours and an estimated
population variance of 3 hours; for University Y, M=6, S2=2; and
for University Z, M=8, S2=1.5. What should you conclude? Use the
0.05 level....
