In a sample from a previous fund raising campaign, the parish found that of the 137 people in the sample they contacted, that 67 actually contributed money. Of those that contributed money, the average contribution was $802 with a standard deviation of $220. In the recent fundraising campaign, a sample of 94 people revealed that 50 have contributed money with an average contribution of $1,165 and a standard deviation of $385.
