To investigate the youth use of the Internet, a sample of 7 adults was asked to report the number of hours they spent on the Internet during the last month. The results are listed below:
52, 87, 60, 39, 42, 50, 40
The researchers claim that the number of hours the adults spent on the Internet exceeds 52 hours per month.
- Find the point estimator of the mean (u) for the number of hours the adults spent on the Internet per month.
- Construct the 90% confidence interval for u. Report the final answer
- Conduct a 5-step test of hypotheses to investigate the researchers claim. Use a=0.10

30–49 answered Yes; 1,061 out of 1,644 adults aged 50 and over
answered Yes. (Round your answers to four decimal places.)

With the increasing use of electronic communications and
Internet, a growing problem among youth is the experience of online
harassment (cyberbullying). Estimates of the extent of
cyberbullying vary. In one national (U.S.) survey conducted in
2005, professional interviewers used random-digit dialing to
construct a sample of 1,500 English-speaking households with youth
between the ages 10 and 17 who use the Internet (Youth Internet
Safety Survey). Youth were interviewed if their parents provided
consent, and the youth assented. Nine percent of...

populations of adults. Can you conclude that the...

A Gallup Poll asked a sample of Canadian adults if they thought
the law should allow doctors to end the life of a patient who is in
great pain and near death if the patient makes a request in
writing. The poll included 255 people in Quebec, 203 of whom agreed
that doctor-assisted suicide should be allowed.
(a) What is the margin of error for a 95% confidence interval
for the proportion of all Quebec adults who would allow
doctor-assisted...

A sample of n = 1,033 adults in the United States was asked, "Do
you think the police should or should not be allowed to collect DNA
information from suspected criminals, similar to how they take
fingerprints?" Of those sampled, 68% answered "should". (Round your
answers to the nearest tenth.)

A poll conducted in 2012 asked a random sample of 1358 adults in
the United States how much confidence they had in banks and other
financial institutions. A total of 149 adults said that they had a
great deal of confidence. An economist claims that less than 13% of
U.S. adults have a great deal of confidence in banks. Can you
conclude that the economist's claim is true? Use both α=0.10 and
α=0.01 levels of significance and the P-value method...
