1. All newbum children are measured and weighed at birth. During the week of Sept lst 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 95 ounces and 120 ounces, respectively and standard deviation 7 ounces. Their lengths (measured {tom the top of their head to the bottom of one of their heels) was normally distributed with mean 18.5 inches and standard deviation 1.5 inches. Outliers were detected among the sample weights and none among the lengths. a. Identify the population in this study. (2 p15,) Population: b. Identify the variables and units: (4 pts.)
