Question
Tin Atte We don't like to find broken crackers when we open the package. How can makers reduce breaking? One idea is to microwave the crackers for 30 seconds right after baking them. Randomly 9 M assign 65 newly baked crackers to the microwave and another 65 to a control group that is not microwaved. After 1 day, none of the microwave group were broken and 16 of the control group were broken. We would like to calculate a confidence interval for p1- P2, the true difference in the proportion of broken crackers in each group. Which of the following conditions are met? I. Independent random samples II. 10% condition III. Large Counts O Il only .O Ill only O All conditions are met O l'and II O None of the conditions have been met O I only
