Question:
The below sample data represents the cost of 9 name-brand drugs and their corresponding generic equivalent. ( Use Name Brand as Sample1 )
| Name Brand | 120 | 150 | 135 | 140 | 160 | 175 | 140 | 120 | 165 |
| Generic Brand | 99 | 135 | 130 | 119 | 139 | 150 | 129 | 109 | 160 |
Note: Do not perform a hypothesis test for this problem. You are to interpret the CI.
- Compute a two-sided 90% confidence Interval estimate for d . (4 points)
- Based on your interval, can you safely conclude that generics are less expensive than name brand? Why or why not? (4 points)
