Consider the following random sample of diameter measurements (in inches) of 19 softballs: 4.85, 4.72, 4.76, 4.68, 4.74, 4.72, 4.9, 4.68, 4.75, 4.69, 4.75, 4.68, 4.71, 4.9, 4.75, 4.89, 4.8, 4.77, 4.86 If we assume that the diameter measurements are normally distributed, find a 99% confidence interval for the mean diameter of a softball. Then complete the table below. Carry your intermediate computations to at least three decimal places. Round your answers to two decimal places. (If necessary, consult a list of formulas.) What is the lower limit of the confidence interval? What is the upper limit of the confidence interval?
