You randomly select 16 coffee shops and measure the temperature of the coffee sold at each. The sample mearn temperature is 162.0°F with a sample standard deviation of 10.0E Construct a 90% and a 99% confidence interval for the population mean temperature of coffee sold in the previous example. Assume the temperatures are approximately normally distributed Compare the widths of the confidence intervals.
