Extracted text: A sample of size n= 60 is drawn from a normal population whose standard deviation is o=9.4. The sample mean is x== 45.87. Part 1 of 2 (a) Construct a 98% confidence interval for u. Round the answer to at least two decimal places. A 98% confidence interval for the mean is Part 2 of 2 (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 vallid since the sample size (Choose one) v large. would/would not Is/is.not Save For Late Continue
