QUESTION 11
A local church parish wants to raise money to add to their
campus. In a sample from a previous fund raising campaign, the
parish found that of the 134 people in the sample they contacted,
that 69 actually contributed money. Of those that contributed
money, the average contribution was $801 with a standard deviation
of $255. In the recent fundraising campaign, a sample of 90 people
revealed that 51 have contributed money with an average
contribution of $1161 and a standard deviation of $385. When
testing (at the 5% level of significance) whether
the variance of the contributions has
increased in the current campaign compared to the previous
campaign, what is the test statistic? (please round your answer to
2 decimal places)
