DELIVERABLE 5 – HYPOTHESIS TESTS FOR TWO SAMPLES

Competency

Formulate and evaluate hypothesis tests for population parameters  based on sample statistics using both Critical Regions and P-Values, and  be able to state results in a non-technical way that can be understood  by consumers of the data instead of statisticians.

Student Profile
You are a statistician working for a drug company. A few new  scientists have been hired by your company. They are experts in  pharmacology, but are not experts in doing statistical studies, so you  will explain to them how statistical studies are done when testing two  samples for the effectiveness of a new drug. The two samples can be  dependent or independent, and you will explain the difference.

Concept being Studied
Your focus is on hypothesis tests and confidence intervals for two  populations using two samples, some of which are independent and some of  which are dependent. These concepts are an extension of hypothesis  testing and confidence intervals which use statistics from one sample to  make conclusions about population parameters.

What to Submit
