Does the average Presbyterian donate a different amount of money compared to the average Catholic in church on Sundays? The 41 randomly observed members of the Presbyterian church donated an average of $29 with a standard deviation of $6. The 48 randomly observed members of the Catholic church donated an average of $27 with a standard deviation of $9. What can be concluded at the = 0.10 level of significance?

1. For this study, we should use Select an answer t-test for the difference between two dependent population means z-test for a population proportion z-test for the difference between two population proportions t-test for a population mean t-test for the difference between two independent population means
2. The null and alternative hypotheses would be:

H0:H0: Select an answer 1 p1 Select an answer < > = Select an answer 2 p2 (please enter a decimal)

H1:H1: Select an answer 1 p1 Select an answer < > = Select an answer p2 2 (Please enter a decimal)

1. The test statistic ? t z = (please show your answer to 3 decimal places.)
2. The p-value = (Please show your answer to 4 decimal places.)
3. The p-value is ? >
4. Based on this, we should Select an answer fail to reject accept reject the null hypothesis.
5. Thus, the final conclusion is that ...

• The results are statistically insignificant at = 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.
• The results are statistically insignificant at = 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.
• The results are statistically significant at = 0.10, so there is sufficient evidence to conclude that the mean donation for the 41 Presbyterians that were observed is a different amount of money compared to the mean donation for the 48 Catholics that were observed.
• The results are statistically significant at = 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.
