Does the average Presbyterian donate less than the average Catholic in church on Sundays? The 46 randomly observed members of the Presbyterian church donated an average of $22 with a standard deviation of $7. The 44 randomly observed members of the Catholic church donated an average of $24 with a standard deviation of $11. What can be concluded at the a = 0.05 level of significance? a. For this study, we should us v Select an answer b.

O The results are statistically significant at o = 0.05, so there is sufficient evidence to conclude that the mean donation for the 46 Presbyterians that were observed is less than the mean donation for the 44 Catholics that were observed. O The results are statistically insignificant at o = 0.05, so there is statistically significant evidence to conclude that the population mean amount of money that Presbyterians donate is equal to the population mean amount of money that Catholics donate. O The results are statistically insignificant at o = 0.05, so there is insufficient evidence to conclude that the population mean amount of money that Presbyterians donate is less than the population mean amount of money that Catholics donate. The results are statistically significant at o = 0.05, so there is sufficient evidence to conclude that the population mean amount of money that Presbyterians donate is less than the population mean amount of money that Catholics donate.Does the average Presbyterian donate less than the average Catholic in church on Sundays?
