Provided below are summary statistics for independent simple random samples from two populations. Use the nonpooled​ t-test and

the nonpooled​ t-interval procedure to conduct the required hypothesis test and obtain the specified confidence interval. x overbar 1equals11​, s 1equals3​, n 1equals25​, x overbar 2equals10​, s 2equals8​, n 2equals20 a.​ Right-tailed test, alphaequals0.05 b. 90​% confidence interval a. What are the hypotheses for the​ t-test? A. H0​: mu1equalsmu2 Ha​: mu1not equalsmu2 B. H0​: mu1equalsmu2 Ha​: mu1greater thanmu2 Your answer is correct.C. H0​: mu1equalsmu2 Ha​: mu1less thanmu2 D. H0​: mu1greater than or equalsmu2 Ha​: mu1less thanmu2 Find the test statistic. tequals . 530 ​(Round to three decimal places as​ needed.) Find the​ P-value. Pequals . 3006 ​(Round to four decimal places as​ needed.) What is the conclusion of the hypothesis​ test? A. Reject H0. There is insufficient evidence that mu1 is greater than mu2. B. Do not reject H0. There is sufficient evidence that mu1 is greater than mu2. Your answer is not correct.C. Do not reject H0. There is insufficient evidence that mu1 is greater than mu2. This is the correct answer.D. Reject H0. There is sufficient evidence that mu1 is greater than mu2. b.

Answer:

Step-by-step explanation:

1km = 1000m

5a. 5.768km = 5768m = 57.7m

5b. 9.039km = 9039m = 90.4m

5c. 8.48km = 8480m = 84.8m

5d. 17.685km = 17685m = 17.7m

5e. 17.658km = 17658m = 17.7m

To round to the nearest 100m just divide by 100 and then round it off. like 57.68=57.7m because 8 is more than 5 so 6 becomes 7 to one decimal.

Rule is applied for all the other questions too.

Vikki [24]
V= \frac{4}{3}  \pi  r^{3} or V=4.1888 r^{3}

r=4 r^{3}=64*4.1888=268.083

V = 268.083 mm^{3} so go with A.
