A sample of size n = 96 is drawn from a normal population whose standard deviation is a = 6.8. The sample mean is x = 49.45. Part 1 of 2 (a) Construct a 98% confidence interval for μ. Round the answer to at least two decimal places. A 98% confidence interval for the mean is Part 2 of 2 <μ< X (b) If the population were not approximately normal, would the confidence interval constructed in part (a) be valid? Explain. The confidence interval constructed in part (a) (Choose one) ▼ be valid since the sample size (Choose one) ▼ large. X
