Question

20.2, 22.4, 30.0, 37.6, 39.8
True or False? These numbers can be used to calculate the standard deviation of the distribution.
Please Answer quickly! I need this done ASAP! Please.

Answer 1

The correct answer is:

False.

Step-by-step explanation:

Using the five number summary, we can estimate the standard deviation.

The quartiles are about 0.67 standard deviations from the mean; this could be used to estimate the standard deviation.

However, we cannot accurately calculate the standard deviation using only the fie number summary.

Answer 2

The answer is False; I put True and it was wrong
