Question:
Suppose that in Exercise 8-14 we wanted the error in estimating the mean life from the two-sided confidence inter- val to be five hours at 95% confidence. What sample size should be used! 817.
Suppose that in Exercise 8-14 we wanted the total width of the two-sided confidence interval on mean life to be six hours at 95% confidence. What sample size should be used? 8:18. Suppose that in Exercise 8-15 it is desired to estimate the compressive strength with an error that is less than 15 psi at 99% confidence. What sample size is required?
