Do cars really get better mileage per gallon on the highway? The table shows results from a study of the MPG (miles per gallon) of cars both in the city and on the highway. Assume that the two samples are randomly selected, independent, the population standard deviations are not know and not considered equal. At the 0.1 significance level, test the claim that the mpg on the highway is better than in the city. MPG on the Highway 35.6 34.3 32.2 33.9 31.1 27.1 33.3 33.4 29.3 33.5 31.4 33.2 33.5 30.8 33.8     MPG in the City 26.4 25.3 18.6 25.6 24.7 24.6 25.1 22.4 29.3 23.7 23.4 22 24 23.6 25.5     What are the correct hypotheses?

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.   Refer to the accompanying data set. Use a 0.05 significance level to test the claim that women and men have the same mean diastolic blood pressure.   a. The test statistic is ​(Round to two decimal places as​ needed.)   b. The​ P-value is ​(Round to three decimal places as​ needed.)

Decide whether the normal sampling distribution can be used. If it can be used, test the claim about the difference between two population proportions p, and p2 at the given level of significance a using the given sample statistics. Assume the sample statistics are from independent random samples. Claim: P1 = P2, a = 0.10 Sample statistics: X1 = 108, n, = 128 and x, = 32, n, = 195 %3D Can a normal sampling distribution be used? No Yes Identify the null and alternative hypotheses. Choose the correct answer below. O A. Ho: P1 = P2 Ha: P1 > P2 В. Но: Р1 <Р2 Ha: P1 = P2 O C. Ho: P1 # P2 Ha: P1 = P2 D. Ho: P1 = P2 Ha: P1 # P2 O E. A normal sampling distribution cannot be used, so the claim cannot be tested.
