Question

Pick any set of data from the textbook or your own data. Conduct a two sample T-test. Explain in the discussion question: Your source of data Your null hypothesis Whether or not you rejected the null hypothesis (and include the P value) How this information might be relevant to a decision maker. Attach the Excel file containing the data source (but be sure everything we need to know about your executive summary is in the body of the discussion forum, not the attachment).

The data from the textbook is as follows:

Professor Andy Neill measured the time (in seconds) required to catch a falling meter stick for 12 randomly selected students' dominant hand and nondominant hand. Professor Neill wants to know if the reaction time in an individual's dominant hand is less than the reaction time in his or her nondomniant hand. A coin flip is used to determine whether reaction time is measured using the dominant or nondominant hand first. The data is obtained below:

Student: Dominant Hand, Xi Non-dominant hand, Yi

1 0.177 0.179   

2 0.210 0.202

3 0.186 0.208

4 0.189 0.184

5 0.198 0.215   

6 0.194 0.193

7 0.160 0.194

8 0.163 0.160

9 0.166 0.209
