Consider the following random sample of diameter measurements (in inches) of 9 softballs. 4.81, 4.72, 4.87, 4.85, 4.83, 4.74, 4.9, 4.77, 4.77 Send data to calculator If we assume that the diameter measurements are normally distributed, find a 95% confidence interval for the mean diameter of a softball. Then find the lower limit and upper limit of the 95% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to two decimal places. (If necessary, consult a list of formulas.) Lower limit: II X 5 2 Upper limit
