Question 4 To test the hypothesis that the population mean mu-7.0, a sample size n=27 yields a sample mean 7.031 and sample standard deviation 0.445. Calculate the P-value and choose the correct conclusion. Your answer: The P-value 0.209 is not significant O and so does not strongly suggest that mu>7.0. The P-value 0.209 is significant and so strongly suggests that mu>7.0. The P-value 0.360 is not significant O and so does not strongly suggest that mu>7.0. The P-value 0.360 is significant and so strongly suggests that mu>7.0. The P-value 0.017 is not significant O and so does not strongly suggest that mu>7.0. The P-value 0.017 is significant and so strongly suggests that mu>7.0. The P-value 0.383 is not significant O and so does not strongly suggest that mu>7.0. The P-value 0.383 is significant and so strongly suggests that mu>7.0. The P-value 0.308 is not significant O and so does not strongly suggest that mu>7.0. The P-value 0.308 is significant and so strongly suggests that mu>7.0.…

● Question 3 Only about 10% of all people can wiggle their ears. Is this percent different for millionaires? Of the 379 millionaires surveyed, 30 could wiggle their ears. What can be concluded at the a = 0.01 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: 80 F3 Ho: ? Select an answer ✓ H₁: ? Select an answer ✓ c. The test statistic ? ✓ = d. The p-value = e. The p-value is ? ✓ a f. Based on this, we should [Select an answer the null hypothesis. g. Thus, the final conclusion is that ... Submit Question (please enter a decimal) O The data suggest the population proportion is not significantly different from 10% at a = 0.01, so there is statistically insignificant evidence to conclude that the population proportion of millionaires who can wiggle their ears is different from 10%. $ (Please enter a decimal) O The data suggest the populaton proportion is significantly different from 10% at a = 0.01, so there is…

QUESTION 25 In a test of hypothesis at a significance level of 1%, the p-value is 0.0029. What is the conclusion of the test? O There is evidence that the null hypothesis is correct. O There is no evidence that the alternative hypothesis is correct. O There is evidence that the alternative hypothesis is correct.
The hypothesis test ?0:?≤74 ?1:?>74is to be carried out for a population where ?σ is known to be 11.1. A random sample has a mean of 75.2 and yields the test statistic of ??=0.59213. What was the size of the sample? ? =
Question 4 Suppose that, for some hypothesis test, a=0.05 and the P-value is computed to be 0.754. What is the appropriate conclusion? Reject the null hypothesis at a significance level of 0.05. It is not possible to make a conclusion based on the information provided. Fail to reject the null hypothesis at a significance level of 0.05. Accept the HO as the "P is low." Further testing is required before it can be determined if we should reject or fail to reject the null hypothesis at a significance level of 0.754.
