A pilot survey was conducted with thirty respondents to examine Internet usage for personal $($nonprofessional$)$ reasons. The attached table contains the resulting data giving each respondent$$s sex $(1=$male, female$=2)$; 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$).$

$1.$ Obtain the frequency distribution of familiarity with the Internet. Calculate the relevant statistics. $($mean$,$ median, mode, variance, sd$,$ range$)$

$2.$ For the purpose of cross$-$tabulation, classify respondents as light or heavy users. Those reporting $5$ 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?
