Does the average Presbyterian donate a different amount of money compared to the average Catholic in church on Sundays? The 55 randomly observed members of the Presbyterian church donated an average of $29 with a standard deviation of $12. The 44 randomly observed members of the Catholic church donated an average of $28 with a standard deviation of $13. What can be concluded at the a = 0.10 level of significance? a. For this study, we should use t-test for the difference between two independent population means b. The null and alternative hypotheses would be: Ho: μ1 H₁: μ1 Ⓒ = O # = Ⓒ μ2 μ2 (please enter a decimal) (Please enter a decimal) c. The test statistic t = 2.158 (please show your answer to 3 decimal places.) d. The p-value (Please show your answer to 4 decimal places.) e. The p-value is ? a f. Based on this, we should Select an answer the null hypothesis. g. Thus, the final conclusion is that ... The results are statistically significant at a = 0.10, so there is sufficient evidence to conclude that the mean donation for the 55 Presbyterians that were observed is a different amount of money compared to the mean donation for the 44 Catholics that were observed. The results are statistically significant at a = 0.10, so there is sufficient evidence to conclude that the population mean amount of money that Presbyterians donate is a different amount of money compared to the population mean amount of money that Catholics donate. The results are statistically insignificant at a = 0.10, 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 a = 0.10, so there is insufficient evidence to conclude that the population mean amount of money that Presbyterians donate is a different amount of money compared to the population mean amount of money that Catholics donate.
