- If an ANOVA test is conducted and the null hypothesis is rejected, what does this indicate? Multiple Choice The p-value is greater than a. At least one pair of population means is different. The population means are equal. All population means are different.Suppose a hypothesis test was performed with a level of significance of 0.05. Then if the null hypothesis is actually true, then there is a 5% chance that the researcher will end up rejecting the null hypothesis in error. True FalseUSA Today reported that about 47% of the general consumer population in the United States is loyal to the automobile manufacturer of their choice. Suppose Chevrolet did a study of a random sample of 1008 Chevrolet owners and found that 487 said they would buy another Chevrolet. Does this indicate that the population proportion of consumers loyal to Chevrolet is more than 47%? Use ? = 0.01. (a) What is the level of significance?State the null and alternate hypotheses. H0: p > 0.47; H1: p = 0.47H0: p = 0.47; H1: p ≠ 0.47 H0: p = 0.47; H1: p < 0.47H0: p = 0.47; H1: p > 0.47 (b) What sampling distribution will you use?

- If you reject the null hypothesis ar the 5% significance level would you reject the null hypothesis at the 3% significance level? Group of answer choices yes no not enough information to determine.I got this answer already, which is B. I got this answer because the p-value is greater than the significance level. This means that "There is NOT sufficient evidence to conclude that the proportion of sales he makes to women is more than 75%." I would like some confirmation whether I am right or wrong.The accompanying table contains the data for the amounts (in oz) in cans of a certain soda. The cans are labeled to indicate that the contents are 16 oz of soda. Use the sign test and a 0.01 significance level to test the claim that cans of this soda are filled so that the median amount is 16 oz. If the median is not 16 oz, are consumers being cheated? Click the icon to view the data. What are the null and alternative hypotheses? O A. Ho: Median volume ≤ 16 oz H₁: Median volume = 16 oz C.

- You are conducting a hypothesis test where alternative (research) hypothesis is that mu is greater than 850. You are testing at the 0.01 significance level. You take a sample of size 64 and calculate your test statistic to be -1.50. What would your test statistic be if you were testing, instead, at the 0.10 significance level?Suppose a hypothesis test will be used to investigate whether the proportion of United States adults who have been a victim of a cybercrime, such as identity theft, is greater than 0.25. Suppose that the hypothesis test is conducted using a significance level of 0.05 and the power of the test is determined for a specific alternative value using the significance level of 0.05. If the significance level of the hypothesis test is changed to 0.01 and the power of the test is computed for the same alternative value using a significance level of 0.01, which of the following best describes the change(s) to the probability of a Type I error and the power of the test? (A) The probability of a Type I error would decrease, and the power of the test would stay the same. (B) The probability of a Type I error would decrease, and the power of the test would increase. (C) The probability of a Type I error would decrease, and the power of the test would decrease. (D) The probability of a Type I error…Does more than 60% of teenagers jog? A survey states, 63% of 45,574 of teenagers surveyed do jog. Use a test of hypothesis to test the validity of the claim. State your conclusion in the context of the problem.
