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, with the following results:

Subject	Before	After
1	172	145
2	164	132
3	168	129
4	158	135
5	183	145

Let μX represent the population mean before treatment and let μY represent the population mean after treatment. Find a 90% confidence interval for the difference μD=μX−μY . Round the answers to three decimal places.

The 90% confidence interval is

23. 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?

Researchers were interested in determining a new drug for reducing high blood pressure. They obtained a sample of volunteers for the study and randomly divided them into two groups, C and T. A single medical practitioner, Dr. Daring, agreed to help the researchers in this study following a protocol of three steps: (i) The blood pressure of each subject was measured by Dr. Daring; (ii) the new drug was administered to subjects in group T and a placebo to subjects...

A pharmaceutical company claims that its new drug reduces systolic blood pressure. The systolic blood pressure (in millimeters of mercury) for nine patients before taking the new drug and 2 hours after taking the drug are shown in the table below. Is there enough evidence to support the company's claim? Let d = (blood pressure before taking new drug) − (blood pressure after taking new drug). Use a significance level of α = 0.05 for the test. Assume that the...

A pharmaceutical company claims that its new drug reduces systolic blood pressure. The systolic blood pressure (in millimeters of mercury) for nine patients before taking the new drug and 2 hours after taking the drug are shown in the table below. Using this data, find the 99% confidence interval for the true difference in blood pressure for each patient after taking the new drug. Assume that the blood pressures are normally distributed for the population of patients both before and...
