Problem 3 A rivet is to be inserted into a hole. A random sample of n = 18 is selected and the hole diameter is measured. The hole diameter is assumed to be normally distributed. The sample variance of the hole diameter of these 18 samples is s? = (0.023)² mm². Construct a 99% two-sided confidence interval on the true o of the hole diameter. Provide an interpretation on your result. [12 points]
