Respuesta :

In normal distributions, the 95th percentile means that a value exists within 2 standard deviations of the mean.

The mean is 175 Lbs and SD is 15 Lbs. This means that Harvey's weight will be within 2 standard deviations (each way) of the mean. I.e. his weight will be in the range 145 - 205 Lbs.
