A survey of nonprofit organizations showed that online fundraising increased in the past year. Based on a random sample of 53 nonprofit organizations, the mean one-time gift donation in the past year was $80, with a standard deviation of $17 If you test the null hypothesis at the 0.10 level of significance, is there evidence that the mean one-time gift donation is greater than $75? b. Interpret the meaning of the p-value in this problem a. a. State the null and alternative hypotheses Choose the correct answer below. ОА. Но и 75 H, HS75 Ос. Но р= 80 Hu> 80 OB HO HS 75 H, με 75 OD. Ho = 80 H, 780 OF. Hous75 H, = 80 EH, 575 H, > 75 Find the test statistic ESTAT = 2.14 (Round to two decimal places as needed.) Find the p-value for this hypothesis test D-value = 0.018 (Round to three decimal places as needed.) What is the conclusion for this test? O A Reject the null hypothesis. There is insufficient evidence that the mean one-time gift donation is greater than $75. O B. Do not reject the null hypothesis. There is insufficient evidence that the mean one-time gift donation is greater than $75. OC. Do not reject the null hypothesis. There is sufficient evidence that the mean one-time gift donation is greater than $75 D. Reject the null hypothesis. There is sufficient evidence that the mean one-time gift donation is greater than $75 b. Interpret the meaning of the p-value in this problem. Choose the correct answer below. O A. The p-value is the probability that the population mean one-time gift donation is $80 or more. OB. The p-value is the probability that the population mean one-time gift donation is $75 given that the sample mean one-time gift donation is $80. OC. The p-value is the probability of getting a sample mean one-time gift donation of $80 or more, given that the population mean one-time gift donation is $75 OD. The p-value is the probability that the population mean one-time gift donation is more than $75.
