Question

**Perform the indicated hypothesis test. Assume that the
two samples are independent simple random samples selected from
normally distributed populations.**

1) A researcher was interested in comparing the amount of time spent watching television by women and by men. Independent simple random samples of 14 women and 17 men were selected, and each person was asked how many hours he or she had watched television during the previous week. The summary statistic are as follows.

Women: xbar1= 12.2hr s1= 4.4 hr n1= 14

Men: xbar2= 17.0 hr s2= 4.7 hr n2= 17

**Use a 0.05 significance level to test the claim that the
mean amount of time spent watching television by women is smaller
than the mean amount of time spent watching television by men. Use
the traditional method of hypothesis testing.**

Thanks.

6) A researcher was interested in comparing the amount of time
(in hours) spent watching television
by women and by men. Independent simple random samples of 14 women
and 17 men were selected, and
each person was asked how many hours he or she had watched
television during the previous week. The
summary statistics are as follows.

Assume that the two samples are independent simple
random samples selected from normally distributed
populations.
Do not assume that the population standard deviations
are equal.
A researcher wishes to determine whether the blood pressure of
vegetarians is, on average, lower than the blood pressure of
nonvegetarians. Independent simple random samples of 85 vegetarians
and 75 nonvegetarians yielded the following sample statistics for
systolic blood pressure
Vegetarians Nonvegetarians n =

In Exercises 5–20, assume that the two samples are independent
simple random samples
selected from normally distributed populations, and do not assume
that the population standard
deviations are equal. (Note: Answers in Appendix D include
technology answers based
on Formula 9-1 along with “Table” answers based on Table A-3 with
df equal to the smaller
of n11 and n21.)

weight of women, and the mean height...

Use the two-proportions z-test to perform the required
hypothesis test. Assume that independent simple random samples have
been selected from the two populations. Use either p-value or
critical-value approach. 1) In a survey, 84 of 185 college
graduates said that they were satisfied in their work, while 76 of
180 adults without a college education said that they were
satisfied with their work. At the 5% significance level, do the
data provide sufficient evidence to conclude that college graduates
are...

Assume that both samples are independent simple random
samples from populations having normal distributions.
4) A researcher obtained independent random samples of men from two
different towns. She recorded the weights
of the men. The results are summarized below:
Town A Town B
n1= 41 n 2 = 21
x1 = 165.1 lb x2 = 159.5 lb
s1 = 34.4 lb s2 = 28.6 lb

variance in...

Assume that the two samples are independent simple random
samples selected from normally distributed populations. Do not
assume that the population standard deviations are equal. Simple
random samples of high-interest (8.7%) mortgages and
low-interest (6.3%) mortgages were obtained. For the 50
high-interest mortgages, the borrowers had a mean credit score of
595.3 and a standard deviation of 12.8. For the 50 low-interest
mortgages, the borrowers had a mean credit score of 761.1 and a
standard deviation of 16.2. Use a...

Independent simple random samples of 950 men and 2500 women are
tested. Among the men in the sample, 81 have red/green color
blindness. Among the women in the sample, 9 have red/green color
blindness.
The value of the test statistic is z= (round
to at least three decimal places).
A sample of 56 students who live on-campus has a mean GPA of
83.7 with a sample standard deviation of 7.44. A independent sample
of 42 students who live off-campus has...
