8.66 Significance Test for Exergaming in Canada. Refer to exercise 8.64. Use a significance test to compare the proportions. Write a short statement interpreting this result.
8.64 Exergaming in Canada. Exergames are active video games
such as rhythmic dancing games, virtual bicycles, balance board
simulators, and virtual sports simulators that require a screen and
a console. A study of exergaming practiced by students from grades
10 and 11 in Montreal, Canada, examined many factors related to
participation in exergaming.22 Of the 358 students who
reported that they stressed about their health, 29.9% said that
they were exergamers. Of the 851 students who reported that they
did not stress about their health, 20.8% said that they were
exergamers.

Perform the indicated goodness-of-fit
test.
Use a significance level of 0.01 to test the claim that workplace
accidents are distributed on workdays as follows: Monday 25%,
Tuesday: 15%, Wednesday: 15%, Thursday: 15%, and Friday: 30%.
In a study of 100 workplace accidents, 25 occurred on a Monday, 17
occurred on a Tuesday, 16 occurred on a Wednesday, 12 occurred on a
Thursday, and 30 occurred on a Friday

In #29-32, use the following information. Use a 0.025 level of
significance to test the claim that vehicle speeds at a certain
location have a mean above 55 km/h . A random sample of 50 vehicles
produces a mean of 61 3. km/h and standard deviation of 3 3. km/h
.

UNDERSTAND HOW TO DO IT! The table below shows the median income
($1000s) and commuter times (minutes) for a random sample of 6
different places. At α = 0.05, can you reject the claim that there
is no correlation between median income and commuting distance?
