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 130 membership member shoppers who recently made a purchase on the web site yielded a mean amount spent of $58 and a standard deviation of $55. 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 $52? a = 0.10 H,:µ = 52 H, :µ + 52 Identify the critical value(s): (Round to two decimal places as needed.) Determine the test statistic: (Round to two decimal places as needed.) State the conclusion:

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 130 membership member shoppers who recently made a purchase on the web site yielded a mean amount spent of $58 and a standard deviation of $55. 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 $52? a = 0.10 H:µ=52 H, :µ + 52 Identify the critical value(s): (Round to two decimal places as needed.) Determine the test statistic: (Round to two decimal places as needed.) State the conclusion: 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 59 nonprofit organizations, the mean one-time gift donation in the past year was $75 with a standard deviation of $20. If 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. you test a = 0.05 H,:uS 70 H, :µ > 70 Find the test statistic: (Round to two decimal places as needed.) Find the p-value: (Round to two decimal places as needed.) State the conclusion:
