Asked by Brianna
According to internal testing done by the Get-A-Grip tire company, the lifetime of tires sold on new cars is normally distributed with a mean of 23,000 miles, with a standard deviation of 2500 miles. If the claim by Get-A-Grip is true, what is the mean of the sampling distribution of x-bar for samples of size n = 4?
