A recent personalized information sheet from your wireless phone carrier claims that the mean duration of all your phone calls w
as μ = 2.9 minutes with a standard deviation of σ = 1.9 minutes. From a random sample of n = 50 calls, your parents computed a sample mean of 
= 3.6 minutes and a sample standard deviation of s = 2.6 minutes.
Sketch the population distribution for the duration of your phone calls. What are its mean and standarddeviation?
