A random sample of single males and single females (ages 21 to 76) was obtained. 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 the relationship. The results of the survey are provided in the table for the trait "stubborn". Is there a significant difference between males and females who consider the trait "stubborn" a relationship deal-breaker? Use the a = 0.05 level of significance.
