A random sample of 52 fatal crashes in 2013 in which the driver had a positive blood alcohol concentration (BAC) from the National Highway Traffic Safety Administration results in a mean BAC of 0.171 gram per deciliter (g/dL) with a standard deviation of 0.009 g/dL.
Determine and interpret a 91% confidence interval for the mean BAC in fatal crashes in which the driver had a positive BAC.
