Are you an impulse shopper? A survey of 800 grocery shoppers indicated that 48% of males and 37% of females make an impulse purchase every time they shop. Assume that the survey consisted of 400 males and 400 females. a. At the 0.01 level of significance, is there evidence of a difference in the proportion of males and females who make an impulse purchase every time they shop? b. Find the p-value and interpret its meaning. Question content area bottom Part 1 a. State the null and alternative hypotheses, where π1 is the population proportion of males who make an impulse purchase every time they shop and π2 is the population proportion of females who make an impulse purchase every time they shop. Choose the correct answer below. A. H0: π1=π2 H1: π1>π2 B. H0: π1≠π2 H1: π1=π2 C. H0: π1≠π2 H1: π1>π2 D. H0: π1≠π2 H1: π1<π2 E. H0: π1=π2 H1: π1<π2 F. H0: π1=π2 H1: π1≠π2 Your answer is correct. Part 2 Determine the value of the test statistic. ZSTAT=enter your response here (Type an integer or a decimal. Round to two decimal places as needed.)
