A certain medicine company wants to determine that if a drug has the undesirable side effect of reducing the blood pressure of the patient. The research involves recording the initial blood pressure 12 certain aged patients. Then, these patients took the druh by the advise of the doctors and at the end of their useahe, the blood pressures of them again recorded. The company would like to draw inferences about the effect of the drug on the blood pressure based on the following data: Patients Blood Pressure 1 2 3 4 5 6 7 8 9 10 11 12 Before usage (x) 77 72 80 64 70 76 72 82 78 74 74 76 After uesage (y) 70 62 72 72 68 66 68 74 52 74 74 58 a) Calculate a 90% CI for the mean reduction in blood pressure. Round your answer to 1 decimal point. b) Do the data provide significant evidence toward the claim on the use of the drug reduces blood pressure? Test at = 0.10. We accept Ho We do not accept Ho

Question
A certain medicine company wants to determine that if a drug has the undesirable side effect of reducing the blood pressure of the patient. The research involves recording the initial blood pressure 12 certain aged patients. Then, these patients took the druh by the advise of the doctors and at the end of their useahe, the blood pressures of them again recorded. The company would like to draw inferences about the effect of the drug on the blood pressure based on the following data:
| Patients | |||||||||||||
| Blood Pressure | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | |
| Before usage (x) | 77 | 72 | 80 | 64 | 70 | 76 | 72 | 82 | 78 | 74 | 74 | 76 | |
| After uesage (y) | 70 | 62 | 72 | 72 | 68 | 66 | 68 | 74 | 52 | 74 | 74 | 58 |
a) Calculate a 90% CI for the mean reduction in blood pressure. Round your answer to 1 decimal point.
b) Do the data provide significant evidence toward the claim on the use of the drug reduces blood pressure? Test at = 0.10.
