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. State the conclusion. evidence at the 0.05 level of significance to conclude that there is a difference in the proportion of males the null hypothesis. There is and females who make an impulse purchase every time they shop. b. Find the p-value in (a) and interpret its meaning. The p-value is (Round to three decimal places as needed.) Interpret the p-value. The p-value is the probability that in a random sample of 800 adults, the difference between the proportions of males and females who make an impulse purchase the difference in this sample, assuming that the proportion of males who make an impulse purchase every time every time they shop will be the proportion for females in the population.
