A national report claims that 70% of people who graduate high school enroll in college. 30 out of the 50 people (who graduated high school) reported that they were enrolled in college. Can you prove their claim that 70% of people who graduate high school enroll in college? Use a .05 level of significance. Formulate the decision rule. (use z or t of -1.54)
- Reject Ho if -1.96 > z > 1.96
- Reject Ho if z < -1.65
- Reject Ho if z > 2.58
- Reject Ho if -1.28 > z > 1.28
