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 68.8 for a sample of size 27 and standard deviation 7.4. Estimate how much the drug will lower a typical patient's systolic blood pressure (using a 99% confidence level). Assume the data is from a normally distributed population. Enter your answer as a tri-linear inequality accurate to three decimal places. ____ < μ < ____

The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 72.4 mmHg (millimeters of mercury) for a sample of size 258 and a sample standard deviation 16.1 mmHg. How much of mmHg will lower for a typical patient's systolic blood pressure after taking the drug? Estimate with a 99% confidence. Preliminary: Is it safe to assume that n≤5% of all patients with a systolic blood pressure? No Yes...

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.

When subjects were treated with a drug, their systolic blood pressure readings (in mm Hg) were measured before and after the drug was taken. Results are given in the table below. Assume that the paired sample data is a simple random sample and that the differences have a distribution that is approximately normal. Using a 0.05 significance level, is there sufficient evidence to support the claim that the drug is effective in lowering systolic blood pressure? Before: 188, 210, 157,...

The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 41 for a sample of size 10 and standard deviation 20. Estimate how much the drug will lower a typical patient's systolic blood pressure (using a 99% confidence level). Give your answers to one decimal place and provide the point estimate with its margin of error.
