Problem:

Use the data values of problem #38 on page 48 in your textbook to find the following:

  1. Compute the mean, median, and mode for the number of hours of PC usage per week.
  2. Determine the standard deviation of the number of hours of PC usage per week.
  3. Using Tchebysheff's theorem, between what values would you expect about 65 percent of the number of hours of PC usage to occur?
  4. Using the empirical rule, about 95 percent of the values would occur between what values?
  5. Determine the coefficient of variation.
  6. Indicate whether the data are skewed or symmetric? Justify your answer.
  7. Calculate the \(25^{\text {th }}\) and \(75^{\text {th }}\) percentile.
  8. Write a brief report summarizing the results.

A recent study of home technologies reported the number of hours of personal computer usage per week for a sample of 60 persons. Excluded from the study were people who worked out of their home and used the computer as a part of their work.
