A researcher wishes to estimate the average blood alcohol concentration (BAC) for drivers involved in fatal accidents who are found to have positive BAC values. He randomly selects records from 51 such drivers in 2009 and determines the sample mean BAC to be 0.17 g/dL with a standard deviation of 0.060 g/dL. Complete parts (a) through (d) below.
