A random sample with n = 25 from the normal distribution N(J, 16) yielded = = 10. Find a 95% confidence interval for u. X O A. (9.35, 12.65) O B. (9.02, 10.98) O C. (7.76, 12.24) O D. (8.43, 11.57) O E. (8.71, 11.29)Refer to Question 14. If we increase the confidence level from 95% to 99%, then the confidence interval will be O A. wider O B. narrower O C. undecided (not have enough information) O D. the same O E. none of the restRefer to Question 14, and denote the confidence interval in Question 14 by Cold. Suppose that we create a new 95% confidence interval for u based on another random sample with 45 observations from the same population, and denote this confidence interval by Clnew- Which statement regarding the comparison between Cold and Clnew is TRUE? A. Clnew is wider than Cold- O B. Clnew and Clold are identical. O C. None of the rest. O D. Clnew is as wide as Cold. O E. Clnew and Clold may have different centers
