THE NEXT QUESTIONS ARE BASED ON THE FOLLOWING INFORMATION:
A process producing bricks is known to produce bricks whose weights are normally distributed with a standard deviation of 0.11 lb.A random sample of 16 bricks from today's output had a mean weight of 4.08 lb.
-Suppose that the population standard deviation for today's output is 0.14 lb (not 0.11 lb).Without doing the calculations,explain whether a correctly calculated 99% confidence interval for the mean weight of today's output would be wider than,narrower than,or the same width as that of a 99% confidence interval calculated using the population standard deviation of 0.11 lb for today's output.
