Need help with statistics 1.b

Brand managers become concerned if they discover that customers are aging and gradually moving out of the high-spending age groups. The average buyer for a particular brand of car is 56. A new model draws in younger customers. If a sample of 49 purchasers of the new model has average age 48 (with standard deviation 26), is this compelling evidence that the buyers of the new model are younger than the typical buyer of the brand? (Assume that the data meet the sample size condition.) Complete parts a through c. liew by SAT purchasers of the new model are not younger when in fact they are is a Type II error. 12 D. Concluding that purchasers of the new model are younger when in fact they are not is a Type I error. Concluding that purchasers of the new model fare not younger and they are not is a Type II error. (c) Find the p-value of the test using a normal model of the sample distribution. Do the data supply enough evidence to reject the null hypothesis if a = 0.025? p-value = (Type an integer or decimal rounded to three decimal places as needed.) Do the data supply enough evidence to reject the null hypothesis if a = 0.025? O A. Reject Ho. There is sufficient evidence that purchasers of the new model are younger than 56 years on average. O B. Fail to reject Ho. There is not sufficient evidence that purchasers of the new model are younger than 56 years on average. O C. Reject Ho. There is not sufficient evidence that purchasers of the new model are younger than 56 years on average. O D. Fail to reject Ho. There is sufficient evidence that purchasers of the new model are younger than 56 years on average
