Question

One barge from inland waterways, inc. can carry a load of 2655 lb. records of past trips show that the weights of the cans that it carries have a mean of 102 lb and a standard deviation of 10 lb. for samples of size 25, find the mean and standard deviation of x

Answer 1

The mean is 102 and the standard deviation is 2.

The sample mean is equal to the population mean; the sample standard deviation is equal to

σ/√n = 10/(√25) = 2
