Show ALL work including steps used during computations using formulas and diagrams when appropriate.

A pharmaceutical company is testing a new cold medicine to determine if the drug has side effects. To test the drug, 7 patients are given the drug and 8 patients are given a placebo (sugar pill). The change in pulse rate (beats per minute) after taking the pill was as follows:

Given Drug: 3 7 2 8 2 5 6
Given Placebo: 2 4 1 1 2 0 2 3

Test to determine if the drug raises patients’ pulse rate more than the placebo using α = 0.025

Solutions

Expert Solution

Let denote mean pulse rate of drug and placebo.

There is sufficient evidence to support the claim that the drug raises patients’ pulse rate more than the placebo.
