Question

What is the rejection region? . If you use statistical software, copy output from statistical software

In many animal societies, a role assumed by the adult male is a sentry, warning adult females and juveniles of approaching predators. Some students of animal behavior believe that this occurs in human society also. In one 4-month study in Seattle an investigator observed people crossing the street at an intersection with no traffic control. The observed behavior was the scanning behavior ("looking both ways") of adult males and females. The investigator reasoned that if the adult male assumed a protective sentry role, the scanning rate when alone would be less than when accompanied by an adult female. Data from this study is given below. Conduct hypothesis test using a=.05.

Male Scanning ("Looking both ways") Behavior Situation            Scanned       Did Not             Totals Scan
Alone	56	28	84
With adult female	61	15	76
