Question: Ages of Motorcyclists Killed in Crashes: Study of the ages of motorcyclists killed in crashes involves the random select ion of 150 drivers with a mean of 34.1 years (based on data from the Insurance Institute for Highway Safety). Assuming that s = 12.0 years, construct a 99% confidence interval estimate of the mean ages of all motorcyclists killed in crashes. If the confidence interval limits do not include ages below 20 years, does it mean that motorcyclists under age of 20 rarely die in crashes?
