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 $1,161 and a standard deviation of $385. When testing at the 5% level of significance) whether the proportion of peole who are contributing has increased, what is the test statistic? (please round your answer to 2 decimal places)
