Please Help TIA

14. In parts (a), (b), and (c) below, determine the confidence interval about the population mean u using the given information. Assume the sample is NOT drawn from a normal population. (a) Given: c = 0.95, x = 26.5, s = 4.8 and n = 41 DO NOT ROUND! The c-confidence interval is: (4 pts) The width of the interval is: (3 pts) Using the width, compute the error E = (3 pts) (b) Given: c = 0.92, X = 114, s = 25.6 and n = 34 DO NOT ROUND! The c-confidence interval is: (4 pts) The width of the interval is: (3 pts) Using the width, compute the error E = (3 pts)
