Below are independent measurements of the diameter(in cm) of cablet bony. manufactured m a plant: 5.300 4.460 5.321 5.729 5.219 5.463 5.325 4.864 Assuming the data is normally distributed with no outliers, find a 90% confidence interval tor ttve diameter of the cable. Suppose we intend to measure the diameter of a ninth cable, find a 90% prediction interval for the measure of the diameter of this cable.
