Problem #2: Students with the last name of F-J: Please review Section 9.2. A marketing researcher wants to estimate the mean amount spent per year ($) on a web site by membership member shoppers. Suppose a random sample of 100 membership member shoppers who recently made a purchase on the web site yielded a mean amount spent of $56 and a standard deviation of $52. Use technology to solve and include files and/or screen shots. Is there evidence that the population mean amount spent per year on the web site by membership member shoppers is different from $51? = 0.05 H:-51 H:#51 Identify the critical value(s): Determine the test statistic: State the conclusion: (Round to two decimal places as needed.) (Round to two decimal places as needed.) Please review Section 9.3. A survey of nonprofit organizations showed that online fundraising increased in the past year. Based on a random sample of 52 nonprofit organizations, the mean one-time gift donation in the past year was $75 with a standard deviation of $13. 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 $70? Use technology to solve and include files and/or screen shots. = 0.05 H: 570 H:>70 Find the test statistic: Find the p-value: State the conclusion: (Round to two decimal places as needed.) (Round to two decimal places as needed.)
