Use Random number generator (under Data Analysis) to create two sets of data each 20 points long. Use the following parameters: number of variables (2), number of data point (20), Distribution (Normal), Mean (30), Standard Deviation (5), Random seed (1332). Perform t-test on these two data sets. And answer the questions for Assessment. (Pick the closest answer)

12. What is the conclusion?

• a. Statistical interpretation agrees with the intuition: data are created with identical means and we can conclusively claim that they have different averages.
• b. Statistical interpretation agrees with the intuition: data are created with identical means and consequently we cannot conclusively claim that they have different averages.
• c. The P-value is large and statistics confirms that the data have identical averages.
• d. None of these
