Fo the data in the worksheet Blade Weight, what is the sampling distribution of the mean, the overall mean, and the standard error of the mean? Is a normal distribution an approproate assumption for the sampling distribution of the mean?

Solution

what is the sampling distribution of the mean, the overall mean, and the standard error of the mean?

sampling distribution of the mean will be xbar

standard error of the mean will be SD / srqt (n)
Is a normal distribution an approproate assumption for the sampling distribution of the mean?

if n > 30 then yes is a normal distribution
