Question
Consider the following random sample of diameter measurements (in inches)of 13 softballs: 4.73, 4.78, 4.76, 4.77, 4.71, 4.69, 4.9, 4.71, 4.89, 4.69, 4.76, 4.85, 4.84
Consider the following random sample of diameter measurements (in inches)of 13 softballs: 4.73, 4.78, 4.76, 4.77, 4.71, 4.69, 4.9, 4.71, 4.89, 4.69, 4.76, 4.85, 4.84
If we assume that the diameter measurements are normally distributed, find a 90% 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
what is the lowest limit of the confidence interval?
what is the highest limit of the confidence interval?
