Suppose X∼B(75,0.28)

  1. For this distribution, is the normal approximation reasonable? Your answer must make reference to skewness.
  2. If you take a sample of size 120, what's the approximate probability that the proportion of successes will be larger than 0.65? (Answer this regardless of your answer to a.)

A tablet PC contains 8152 music and video files. The distribution of file size is highly skewed. Assume that the standard deviation for this population is 0.82 megabytes (MB). (a) What is the standard deviation of the average file size when you take an SRS of 40 files from this population? (b) How many files would you need to sample if you wanted the standard deviation of ¯x to be no larger than 0.10 MB? (c) Explain why it may...
