All new-born children are measured and weighed at birth. During the week of Sept 1st to 5th, 25 babies were born. Their weights (in ounces) and lengths (in inches) were recorded. The mean and median weights for the sample of 25 babies were 120 ounces and 95 ounces, respectively and standard deviation 6 ounces. Their lengths (measured from the top of their head to the bottom of one of their heels) was normally distributed with mean 18.50 inches and standard deviation 1.25 inches. Outliers were detected among the sample weights and none among the lengths.

normally distributed with mean 18.50 inches and standard deviation 1.25 inches. Outliers were detected
among the sample weights and none among the lengths.
