The random sample shown below was selected from a normal distribution. 4, 7, 10, 7, 3, 5 Complete parts a and b. **** a. Construct a 95% confidence interval for the population mean μ. 3.35,8.65) (Round to two decimal places as needed.) b. Assume that sample mean x and sample standard deviation s 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 . (Round to two decimal places as needed.)
