Transcribed Image Text:Watching TV: In 2012, the General Social Survey asked a sample of 1326 people how much time they spent watching TV each
day. The mean number of hours was 3.02 with a standard deviation of 2.64. A sociologist claims that people watch a mean of 3
hours of TV per day. Do the data provide sufficient evidence to conclude that the mean hours of TV watched per day differs from
the claim? Use the a=0.05 level of significance and the P-value method vaith the TI-84 Plus calculator.
Part 1 of 4
(a) State the appropriate null and alternate hypotheses.
H u = 3
This hypothesis test is a two-tailed
test.
Part 2 of 4
(b) Compute the P-value. Round the answer to at least four decimal places.
P-value =0.7827
Part 3 of 4
(c) Determine whether to reject Ho
Do not reject the null hypothesis H
Part: 3/4
Part 4 of 4
(d) State a conclusion.
There is not
enough evidence to conclude that the mean time watching TV differs
from 3 hours.
