Hello,

I am going in a circle with the below questions. I followed the examples in the textbook and I tried to solve a few of the exercises practice. However, some of the examples can be very complex to solve.

Could you please explain the following questions in detail? I am unsure about the answer. Your assistance would be greatly appreciated.

1. The commissioner of the state police is reported as saying that about 10% of reported auto thefts involve owners whose cars haven't really been stolen. What null and alternative hypotheses would be appropriate in evaluating this statement made by the commissioner? O A. Ho: p s 0.10 and H,: p > 0.10 O B. Ho: p = 0.10 and H1: p # 0.10 O C. Ho: p 2 0.10 and H1: p 0.10 and H1: p s 0.103. In sampling without replacement from a population of 900, it's found that the standard error oi the mean, a", is only two-thirds as large as it would have been if the population were infinite in size. What's the approximate sample size? 0 A. 400 O B. 600 O C. 500 O D. 200 9. Where is the rejection region if t > 1.440 and df = 6? O A. a = .05 O B. a = .01 O C. a = .02 O D. a = .1010. Researchers conduct an online survey of American adults to determine their favorite sport. About 90% of American adults consider themselves sports fans. You believe that professional football will be determined to be the favorite sport for 40% of American adults. Professional football brings in 36% of all annual revenue for ads for televised events. Specify the null and alternative hypothesis for your belief that professional football is the favorite sport of American adults. O A. Ho : P = .4, Ha : p #.4 O B. Ho : p = .9, Ha : p#.9 O C. Ho : p = .36, Ha : p #.36 O D. Ho : p = .6, Ha : p #.6
