Does the average Presbyterian donate more than the average Catholic in church on Sundays? The 56 randomly observed members of the Presbyterian church donated an average of $24 with a standard deviation of $15. The 42 randomly observed members of the Catholic church donated an average of $21 with a standard deviation of $11. What can be concluded at the αα = 0.01 level of significance?   The p-value =  (Please show your answer to 4 decimal places.) The p-value is     α Thus, the final conclusion is that ... The results are statistically significant at αα = 0.01, so there is sufficient evidence to conclude that the population mean amount of money that Presbyterians donate is more than the population mean amount of money that Catholics donate. The results are statistically insignificant at αα = 0.01, 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 αα = 0.01, so there is insufficient evidence to conclude that the population mean amount of money that Presbyterians donate is more than the population mean amount of money that Catholics donate. The results are statistically significant at αα = 0.01, so there is sufficient evidence to conclude that the mean donation for the 56 Presbyterians that were observed is more than the mean donation for the 42 Catholics that were observed.

Does the average Presbyterian donate more than the average Catholic in church on Sundays? The 56 randomly observed members of the Presbyterian church donated an average of $24 with a standard deviation of $15. The 42 randomly observed members of the Catholic church donated an average of $21 with a standard deviation of $11. What can be concluded at the αα = 0.01 level of significance?  

  1. The p-value =  (Please show your answer to 4 decimal places.)
  2. The p-value is     α
  3. Thus, the final conclusion is that ...
    • The results are statistically significant at αα = 0.01, so there is sufficient evidence to conclude that the population mean amount of money that Presbyterians donate is more than the population mean amount of money that Catholics donate.
    • The results are statistically insignificant at αα = 0.01, 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 αα = 0.01, so there is insufficient evidence to conclude that the population mean amount of money that Presbyterians donate is more than the population mean amount of money that Catholics donate.
    • The results are statistically significant at αα = 0.01, so there is sufficient evidence to conclude that the mean donation for the 56 Presbyterians that were observed is more than the mean donation for the 42 Catholics that were observed.
