A machine produces metal rods used in an automobile suspension system. A random sample of 15 rods is selected, and the diameter is measured. The resulting data (in millimeters) are as follows: 8.24, 8.25, 8.20, 8.23, 8.24, 8.21, 8.26, 8.26, 8.20, 8.25, 8.23, 8.23, 8.19, 8.28, 8.24. How many more samples do you need to collect to estimate the mean to within 0.005 mm with 95% two-sided confidence? Assume degrees of freedom is 14 for the t distribution for calculation of this problem. Please report your answer as a whole number.
