Question

The weights of Labrador Retrievers are normally distributed with a mean of 72 pounds with a standard deviation of 3.5 pounds. Provide a distribution for representative, random samples of 50 Labradors.

Answer 1

Solution :

Given that ,

mean = =72

standard deviation = = 3.5

n = 50

sample distribution of sample mean is ,

=

= 72

sampling distribution of standard deviation

=  / n = 3.5/ 50

= 0.49

approximately normal distribution
