A random sample of single males and single females (aged 21 to 76) was obtained by a group called Singles in America. The sample includes those currently separated, divorced, or widowed. The subjects were given a trait and asked to respond whether the trait was a deal breaker in terms of maintaining a relationship. For each trait given in parts (a) through (c), determine if there is a statistically significant difference in the proportion of individuals responding yes. If there is a significant difference, report a 95% confidence interval for the difference.
