C] Reject the null hypothesis that the percentage of adults who have a job is equal to 88% when that percentage is actually equal to 88%. 2. C] Reject the null hypothesis that the percentage of adults who have a job is less than 88% when that percentage is actually less than 88%. 3.

The Kaiser Medical Foundation claims that the cost to rehabilitate a football player following a head injury is $28,500. To test this claim a researcher surveys the medical billing records of 45 football players who were treated for head injuries. The average cost for rehabilitation in this randomly selected sample is $30,885 with a standard deviation of $1 ,123. Is the actual cost of rehabilitation $28,500 as Kaiser claims? Please select al TRUE statements for this hypothesis test. Answer 1. _ Ho: u = $28,500 and H1: u at $28,500 H0: u 5 $28,500 and H1: u > $28,500 For this hypothesis test the P-value = 4.91 2. 3. 4. For this hypothesis test the P-value = O 5. _ We decide to "support" Kaiser's claim that the cost to rehabilitate a football player following a head injury is $28,500. An IQ test is designed so that the mean is 100 and the standard deviation is 13 for the population of normal adults. Find the sample size necessary to estimate the mean IQ score of statistics students such that it can be said with 99% confidence that the sample mean is within 4 IO points of the true mean. Determine the required sample size using the Tl-83/84. The required sample size is (Round UP to the nearest integer.) Answer [x Fa [a i new les]
