A simple random sample of IQ scores is selected from a normally distributed population of statistics professors. The sample statistics are n = 20, x= 126, s=11. Determine the critical value of t an the margin of error, and then construct the 95% confidence interval estimate for the population mean. The critical value is t = (Round to three decimal places as needed.) The margin of error is. (Round to three decimal places as needed.) Find the 95% confidence interval.
