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, 4.86If we assume that the diameter measurements are normally distributed, find a 99% confidence interval forthe 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 decimalplaces. (If necessary, consult a list of formulas.)What is the lower limit of the confidenceinterval?What is the upper limit of the confidenceinterval?

From the provided information, Sample size (n) = 19 The mean of the data can be obtained as:
