Question26) Formulate the indicated conclusion in nontechnical terms. Be sure to address the original claim. Carter Motor Company claims that its new sedan, the Libra, will average better than 32 miles 26) \qquad per gallon in the city. Assuming that a hypothesis test of the claim has been conducted and that the conclusion is to reject the null hypothesis, state the conclusion in nontechnical terms. A) There is sufficient evidence to support the claim that the mean is less than 32 miles per gallon. B) There is not sufficient evidence to support the claim that the mean is less than 32 miles per gallon. C) There is sufficient evidence to support the claim that the mean is greater than 32 miles per gallon. D) There is not sufficient evidence to support the claim that the mean is greater than 32 miles pergallon. 27) Use the given information to find the PP-value. Also, use a 0.05 significance level and state the conclusion about the null hypothesis (reject the null hypothesis or fail to reject the null 27) \qquad hypothesis). With H1:p3/5H_{1}: p \neq 3 / 5, the test statistic is z=0.78z=0.78. A) 0.2177 ; reject the null hypothesis B) 0.4354 ; reject the null hypothesis

Studdy Solution
For problem 26, the correct answer is C: There is sufficient evidence to support the claim that the mean is greater than 32 miles per gallon.
For problem 27, the p-value is 0.43540.4354.
Since 0.4354>0.050.4354 > 0.05, we fail to reject the null hypothesis.
