A newspaper publisher believes that over 47% of their readers own a Rolls Royce. For marketing purposes, a potential adveriser wants to confirm this claim. After performing a test at the 0.02 level of significance, the advertiser failed to reject the null hypothesis. What is the conclusion regarding the publisher's claim? (Choose A or B) A. There is sufficient evidence at the 0.02 level of significance that the percentage is over 47%. B. There is not sufficient evidence at the 0.02 level of significance to say that the percentage is over 47%.

5. In a certain county, the local newspaper reports that the average family income for that county is $45,000. Economists at the university believe that first-time home buyers have an average family income which is higher than this. Which of the following hypotheses would be appropriate for a significance test? Ho: u= 45, 000 Ha: µ# 45, 000 b. H.: u= 45, 000 Ha: µ> 45, 000 H.: u= 45, 000 Ha: u 45, 000 Ha: u = 45, 000 a. C. е.

(c) Decide whether to reject or fail to reject the null hypothesis. Which of the following is correct? O A. Fail to reject H, because the P-value is greater than the significance level. O B. Reject Hn because the P-value is less than the significance level. O C. Fail to reject H, because the P-value is less than the significance level. O D. Reject H, because the P-value is greater than the significance level. (d) Interpret the decision in the context of the original claim. O A.
