The random sample shown below was selected from a normal distribution 9,5,6,583 Complete parts a and b a. Construct a 90% confidence interval for the population mean (14 20 780) (Round to two decimal places as needed) b. Assume that sample mean x and sample standard deviations remain exactly the same as those you just calculated but that are based on a sample of n-25 observations Repeat part a What is the effect of increasing the sample size on the width of the confidence intervals? The confidence interval is I (Round to two decimal places as neded
