Deliverable 05 – WorksheetInstructions: The following worksheet describes two examples – one is an example for independent samples and the other one for dependent samples. Your job is to demonstrate the solution to each scenario by showing how to work through each example in detail. You are expected to explain all of the steps in your own words.1) Independent samples:One of our researchers wishes to determine whether people with high blood pressure can reduce their systolic blood pressure by taking a new drug we have developed. Thesample data is shown below, where xx1represents the mean blood pressure of the treatment group and xx2represents the mean for the control group. Use a significance level of 0.05 and the critical value method to test the claim that the diet reduces the blood pressure. We do not know the values of the population standard deviations. Please use the following critical value for this test: t 2.378TREATMENT GROUPCONTROL GROUPN185n275´x1189.1´x2203.7s138.7s39.2.2
In this scenario the null hypothesis would be that there is no change or effect on the blood pressure between the treatment group receiving the newly developed blood pressure drug and the control group’s blood pressure. This would be represented by the following symbolic form: Ho: μ1=μ2. What we are testing is that the newly
