28
30

31
32
35

38

10) Calculate the standard deviation, variance, and the z-score of someone with a BMI at 21.

11) Is this z-score unusually high or low? (If yes, specify which one).

12) Identify the 5-number summary below

13) Calculate the IQR

14) Identify any outliers

15) Draw a boxplot of your data (modified for outliers)

16) Write a sentence describing the shape of the distribution (skewed or symmetric).

17) How close together are your mean and median? Does this support your thoughts of skewness or symmetry for #16?

Use the empircal rule to answer the following:

1) Assume the mean is 29 and the standard deviantion is 2. Draw the curve, identify the mean at the center, count out the standard deviations from the center.

2) What is the probability someone has a BMI between 27 and 33?

3) What BMI's indicate the lowest 16% and highest 16%?
