A researcher wants to determine if the number of minutes spent
watching television per day is independent of gender. A random
sample of 315 adults was selected and the results are shown below.
Is there enough evidence to conclude that the number of minutes
spent watching television per day is related to gender? Test at the
alpha=0.05 level of significance. Please show all
work/calculations.

An educational organization in California is interested in
estimating the mean number of minutes per day that children between
the age of 6 and 18 spend watching television per day. A previous
study showed that the population standard deviation was 21.5
minutes. The organization selected a random sample of n = 251
children and recorded the number of minutes of TV that each person
watched on a particular day. The mean time was 171.3 minutes. If
the leaders of the...

The average number of minutes individuals spend on the computer
during a day is 134 minutes and the standard deviation is 25
minutes. The number of minutes individuals spend on the computer
during a day is normally distributed. If one individual is randomly
selected, find the probability that their average number of minutes
spent on the computer is (Show your work to receive credit):
a) More than 164 minutes
b) Less than 118 minutes

A social scientist suspects that the mean number of years of
education for all adults in a large city is greater than 12 years.
She will test her hypothesis using a random sample of 100 adults
and finds the sample mean number of years is 12.98. Assume the
standard deviation of the number of years of education for all
adults is 3. State the appropriate null and alternative
hypotheses.
From the previous problem, find the value of the test
statistic....
