Question
K Are you an impulse shopper? A survey of 800 grocery shoppers indicated that 18% of males and 50% of females make an impulse purchase every time they shop. Assume that the survey consisted of 400 males and 400 females. Complete parts (a) and (b) below. to search a. At the 0.05 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: ₁2₂ Н1: П1 <П2 OC. Ho: 1₂ H₁: ₁ = ₂ OE. Ho: ₁₂ H₁: Jy ≤₂ Calculate the test statistic. XSTAT = #10 밥 C L CHEFEND + OB. Ho: ₁₂ H₁: ₁ #₂ OD. Ho: ₁₂ H₁:₁₂ OF. Ho: <₂ H₁: ₁2₂ fo 144 fio 86°F
