Part II. True or False (5 points) Please type TRUE or FALSE on the line 1. If a sample has a variance of 16, then the sample standard deviation must be 4. 2. A population of N=5 scores has ss-20. The variance for this population is 4. 3. For a positively skewed distribution, a z-score of zero will be located below (to the left of) the mean. 4. on an exam with = 70, you have a score of X-76. In this situation, you should expect a better grade if = 3 than if = 12 5. Transforming X values into z-scores will not change the shape of the distribution. Part IlI. Short Answer (Each question is worth 2 points. Total points- 10) Please type answers in the space below each question

Explanation / Answer

1. True since SD= Sqrt(variance) = sqrt(16) = 4
2. True since population variance = SS/N = 20/5 = 4
3. True since Mean>Medain>Mode
4. True since Less SD is more better expect
5. True
