12) The 2008GSS asked respondents whether they used a computer at work or not. We assume that this will be overwhelmingly true for the younger generation, with older generations using computers less. Surprisingly, the relationship goes in the opposite direction: 74% of 18-39-year- olds use a computer at work, compared to 77% of 40-59-year-olds, and 83% of those aged 60 and over. Is this difference within the sample large enough to claim that there exists a difference in the population? Run a chi-square test on the crosstab and formally test this hypothesis.
