Refer to exercise 30 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 files. Exercise 30: A tablet PC contains 3217 music files. The distribution of file size is highly skewed with many small file sizes. Assume that the stnadard deviaiton for this population is 3.25 megabytes (MB) a) Explain why it may be reasonable to assume that the average x, with line on top of it (mean) is approximately normal even though the population distribution is highly skewed. b) Sketch the appoximate normal curve for the sample mean, making sure to specify the mean and stanadard deviation. c) What is the probability that your sample mean will differ from the population mean by more than 0.15 MB?
