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 150 membership member shoppers who recently made a purchase on the web site yielded a mean amount spent of $55 and a standard deviation of $52. Complete parts (a) and (b) below. a. Is there evidence that the population mean amount spent per year on the web site by membership member shoppers is different from $52? (Use a 0.10 level of significance.) State the null and alternative hypotheses. Ho: H 52 H1:µ # 52 (Type integers or decimals. Do not round. Do not include the $ symbol in your answer.) Identify the critical value(s). The critical value(s) is/are. (Type an integer or a decimal. Round to two decimal places as needed. Use a comma to separate answers as needed.)
