B) 22
C) 38
D) 39

Margin of Error

A statistic expressing the amount of random sampling error in a survey's results, defining a range within which the true population parameter is expected to lie with a certain level of confidence.

Normally Distributed

Describes a statistical distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.

Standard Deviation

A measure of the amount of variance or dispersion of a set of values, indicating how much the values in a dataset deviate from the mean.
