Assume that the population standard deviation is σ= 7 seconds. Round the critical value to no less than three decimal places.
(a) Construct a 99% confidence interval for the mean time needed to step. Round the answer to at least one decimal place.
(b) Find the sample size needed so that a 95% confidence interval will have margin of error of 1.5.
A sample size of __ is needed in order to obtain a 95% confidence interval with a margin error of 1.5. Round the sample size up to the nearest integer.
