A pilot survey was conducted with thirty respondents to examine Internet usage for personal (nonprofessional) reasons. The following table contains the resulting data giving each respondent's sex $(1=$ male, $2=$ female $)$; familiarity with the Internet $(1=$ very unfamiliar, 7 = very familiar); Internet usage in hours per week; attitude toward Internet and toward technology, both measured on a 7 -point scale ( 1 = very unfavorable, $7=$ very favorable); and whether the respondent shopped or banked online $(1=$ yes, $2=$ no).

a. Obtain the frequency distribution of familiarity with the Internet. Calculate the relevant statistics.

b. For the purpose of cross-tabulation, classify respondents as light or heavy users. Those reporting five hours or less usage should be classified as light users and the remaining as heavy users. Run a cross-tabulation of sex and Internet usage. Interpret the results. Is Internet usage related to one's sex?
