3. Describing Data Numerically

Suppose you use a graphing calculator to generate a table of summary statistics for two data sets, A and B. Data set A has a mean of $50$ and a standard deviation of $5$, while data set B has a mean of $50$ and a standard deviation of $15$. Which generalization is most accurate based on these statistics?

Which of the following best describes a piece of data that is expressed in numbers $\mathrm{and}$ percentages $\%$ when using a graphing calculator to summarize data?
