A group of five individuals with high blood pressure were given a new drug that was designed to lower blood pressure. Systolic blood pressure was measured before and after treatment for each individual. The mean and standard deviation for the before treatment were 168.6 and 9.3, respectively. The mean and standard deviation for the after treatment were 137.2 and 7.4. respectively. The 90% confidence for the mean reduction in systolic blood pressure is nearly ?

The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 29.1 for a sample of size 928 and standard deviation 16.6. Estimate how much the drug will lower a typical patient's systolic blood pressure (using a 90% confidence level).

The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 42.8 mmHg (millimeters of mercury) for a sample of size 493 and a sample standard deviation 17.5 mmHg. How much of mmHg will lower for a typical patient's systolic blood pressure after taking the drug? Estimate with a 98% confidence. Preliminary: Is it safe to assume that n≤5% of all patients with a systolic blood pressure? No Yes...
