Suppose the null hypothesis is not rejected. State the conclusion based on the results of the test. Three years ago, the mean price of a single-family home was $243,712. A real estate broker believes that the mean price has increased since then. Which of the following is the correct conclusion? A. There is not sufficient evidence to conclude that the mean price of a single-family home has not changed. B. There is not sufficient evidence to conclude that the mean price of a single-family home has increased. C.

One personality test available on the World Wide Web has a subsection designed to assess the "honesty" of the test-taker. You are interested in the mean score, μ, among the general population on this subsection. The website reports that u is 148, but you have good reason to believe that u differs from 148. You decide to do a statistical test. You choose a random sample of people and have them take the personality test. You find that their mean score on the subsection is 155 and that the standard deviation of their scores is 22. Based on this information, complete the parts below. (a) What are the null hypothesis Ho and the alternative hypothesis H, that should be used for the test? H:0 H₁ :0 (b) Suppose that you decide to reject the null hypothesis. What sort of error might you be making? (Choose one) ▼ (c) Suppose the true mean score among the general population on the subsection is 148. Fill in the blanks to describe a Type I error. A Type I error would be (Choose one) when, in fact,…

The accompanying table gives amounts of arsenic in samples of brown rice from three different states. The amounts are in micrograms of arsenic and all samples have the same serving size. The data are from the Food and Drug Administration. Use a 0.05 significance level to test the claim that the three samples are from populations with the same mean. Do the amounts of arsenic appear to be different in the different states? Given that the amounts of arsenic in the samples from Texas have the highest mean, can we conclude that brown rice from Texas poses the greatest health problem? Click the icon to view the data.
