5.32 Average file size on a tablet. Suppose that the true mean file size of the music and video files on the tablet is 2.35 MB and you plan to take an SRS of n=50, the standard deviation of the population is 3.25 MB.

a.) explain why it may be reasonable to assume that the average mean is approximately Normal even though the population distribution is highly skewed?

b.) sketch the approximate normal curve for the sample mean, making sure to specify the mean and standard deviation

c.) what is this probability that you sample mean will differ from the population mean more than .15 MB
