Are you an impulse shopper? A survey of 700 grocery shoppers indicated that 22% of males and 36% of females make an impulse purchase every time they shop. Assume that the survey consisted of 350 males and 350 females. Complete parts (a) and (b) below. 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? Let group 1 be the males, and let group 2 be the females. State the null and alternative hypotheses. Choose the correct answer below. OA. Ho: ₁₂ H₁₁₂ OC. Ho%2 E. Ho: ₁ = H₁₁₂ Calculate the test statistic. XSTAT = (Round to three decimal places as needed.) Determine the critical value. The critical value is (Round to three decimal places as needed.) State the conclusion. the null hypothesis. There is OB. Ho₁₂ H₁₁₂ OD. Ho: # <*2 H₁₁₂ OF. Ho: 2 H₁₁₂ evidence at the 0.01 level of significance to conclude that there is a difference in the proportion of males and females who make an impulse purchase every time they shop.
