Fossils The data in the table are the diameters and heights of 10 fossil specimens of a species of small shellfish that were unearthed in a mapping expedition near the Antarctic Peninsula.16 The table gives an identification symbol for the fossil specimen, the fossil’s diameter and height in millimeters, and the ratio of diameter to height.
a. Find a 95% confidence interval for the mean diameter of the species.
b. Find a 95% confidence interval for the mean height of the species.
c. Find a 95% confidence interval for the mean ratio of diameter to height.
