Question

A random sample of 100 students at a high school was asked
whether they would ask their parent(s) for help with a financial
problem, in which 47 of them replied yes. A second sample of 100
different students was asked the same question regarding a dating
problem, in which 43 of them replied yes. Construct a 98%
confidence interval for *p1-p2,* the difference in the
population proportions of high school students that would ask their
parents for financial help versus a dating problem. Is it possible
that the two population proportions are actually equal? Why or why
not?

A random sample of 200 freshman and 100 seniors at
Ferris High School are asked whether they agree with a plan to
excuse upper class students (juniors and seniors) a half hour early
while keeping underclass students (freshmen and sophomores) in
school for the last half hour. Of the students sampled, 160
freshmen opposed the plan and 20 seniors opposed the plan.
Is there a difference (5% level of significance) between the
proportion of freshmen who oppose the plan and...

A geography test was given to a simple random sample of 250 high
school students in a certain large school district. One question

find Great Britain. Is this difference statistically
significant?

Students at a local elementary school were randomly selected to
participate in a reading fluency program. The program is designed
to increase their reading fluency. A total of 17 students each took
a pretest before the program and posttest after the program. The
mean differences in the posttest and pretest is 11. The
administration decided that all students in the school would
participate in the program next school year. Let µA denote the mean
score of the...

A school psychologist is interested in whether time has changed
the problem with student parking that has been discussed for a few
years. As the student population has grown the psychologist fully
suspects that the time to find parking has become worse rather than
better for the student body. Over the past decade the average
amount of time to find parking for students is 15 minutes (µ=15).
The current sample’s information is as follows: M=19 minutes and a
S= 6...

An organization surveyed 1000 teens and 1000 parents of teens to
learn about how teens are using social networking sites such as

and were chosen in a way that makes it reasonable to regard them as
representative of American teens and parents of American teens.
(a) When asked if they check their online social networking
sites more than 10 times a day, 223 of the teens surveyed said yes.
