Suppose that the times it takes adult women to run a mile are normally distributed with an unknown mean and standard deviation. The mile times of 29 randomly sampled adult women are used to estimate the mean of the population. Use Excel to calculate the t-score that should be used to find the 95% confidence interval for the population mean. Round your answer to three decimal places.

Afactory makes propeller drive shafts for ships. a quality assurance engineer at the factory needs to estimate the true mean length of the shafts. she randomly selects four drive shafts made at the factory, measures their lengths, and finds their sample mean to be 1000 mm. the lengths are known to follow a normal distribution whose standard deviation is 2 mm. calculate a 95% confidence interval for the true mean length of the shafts. input your answers for the margin of error, lower bound, and upper bound.
