Problem #5: Students with the last name of U-Z: 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 $50 and a standard deviation of $56. 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=0.05 H* 52 Identify the critical value(s): (Round to two decmal places as needed.) Determine the test statistic: (Round to two decimal places as needed.) State the conclusion:
