A survey of nonprofit organizations showed that online fundraising increased in the past year. Based on a random sample of 51 nonprofit organizations, the mean one-time gift donation in the past year was $80, with a standard deviation of $18. a. If you test the null hypothesis at the 0.05 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. State the null and alternative hypotheses. Choose the correct answer below. OA. H₂75 H₁>75 OC. H: 80 H₁80 OE. Hu≤75 H₁μ=80 Find the test statistic. ISTAT = (Round to two decimal places as needed.) Find the p-value for this hypothesis test. p-value = (Round to three decimal places as needed.)

There is sufficient evidence that the mean one-time gift donation is greater than $75. C. Reject the null hypothesis. There is insufficient evidence that the mean one-time gift donation is greater than $75. O D. Do not 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. OA. 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 of getting a sample mean one-lime gift donation of $80 or more, given that the population mean one-time gift donation is $75, OC. The p-value is the probability that the population mean one-time gift donation is more than $75. OD. 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.
