In a sample from a previous fund raising campaign, the parish found that of the 136 people in the sample they contacted, that 69 actually contributed money, of those that contributed money, the average contribution was $831 with a standard deviation of $274. In the recent fundraising campaign, a sample of 94 people revealed that 49 have contributed money with an average contribution of S1,189 and a standard deviation of $346.
