1. The number of violent crimes committed in a day possesses a normal distribution with a mean of 3.8 crimes per day and a standard deviation of 2 crimes per day. A random sample of 15 days was observed, and the mean number of crimes for the sample was calculated. Would it be appropriate to use the normal distribution to find the probabilities involving the mean number of violent crimes per day?
