A) The mean is _. * b) The standard deviation is _. *

c) Approximately _ % of the data values fall between 223 and 237. *

This is a required question
d) Approximately _ % of the data values fall between 216 and 244.

e) Approximately _ % of the data values fall between 209 and 251.

If all of the observed values in a sample are close to the sample mean, the standard deviation will be small (i.e., close to zero), and if the observed values vary widely around the sample mean, the standard deviation will be large. If all of the values in the sample are identical, the sample standard deviation will be zero.

Step-by-step explanation:
