Let p1 be the population proportion of all married couples who have two or more personality preferences in common. Let p2 be the population proportion of all married couples who have no personality preferences in common. (a) Find a 90% confidence interval for p1 - p2. (Use 4 decimal places.) Lower Limit Upper Limit (b) Choose the correct conclusion We can not say that a higher proportion of married couples have two or more personality preferences in common. O We can say with 95% confidence that a higher proportion of married couples have no personality preferences in common. We can say with 95% confidence that a higher proportion of married couples have two or more personality preferences in common
