The printout below contains summary statistics of the heights of
a sample of 200 adult men in the United States.
Descriptive Statistics: HT
| Variable | N | Mean | StDev | Minimum | Q1 | Median | Q2 | Maximum |
| HT | 200 | 70.187 | 2.716 | 62.375 | 67.875 | 69.625 | 71.500 | 91.125 |
Use the information in the printout to determine whether the distribution of heights is approximately normal. Explain your reasoning.
Homework Answers
The distribution is not Normal
Explanation- as the mean and median are approximately same but this alone does not decide that it is normal.
Now distance of minimum value from mean is approx 8 and maximum value from mean is 21
These two values should be same then it will show that the distribution is symmetric.
Hence the distribution is not symmetric, the distribution is not normal
