Use Single-Value Grouping to Organize These Data into a Frequency

Use single-value grouping to organize these data into a frequency distribution.
-The following data represent the total number of years of formal education for 40 employees of a bank. $\begin{array} { l l l l l l l l l l } 13 & 17 & 13 & 14 & 12 & 17 & 19 & 13 & 15 & 13 \\ 16 & 18 & 13 & 11 & 19 & 19 & 12 & 14 & 13 & 13 \\ 14 & 15 & 13 & 15 & 17 & 18 & 17 & 14 & 13 & 17 \\ 12 & 17 & 17 & 16 & 16 & 17 & 15 & 13 & 13 & 14 \end{array}$
Construct a frequency distribution for the number of years of education.

A)
$\begin{array}{r|r}\begin{array}{r}\text { Number of } \\\text { years of }\end{array} & \\\text { education } & \text { Frequency } \\\hline 11 & 1 \\12 & 3 \\13 & 11 \\14 & 5 \\15 & 4 \\16 & 3 \\17 & 8 \\18 & 2 \\19 & 3\end{array}$


B)
$\begin{array}{r|r}\begin{array}{r}\text { Number of } \\\text { years of }\end{array} & \\\text { education } & \text { Frequency } \\\hline 11 & 1 \\12 & 3 \\13 & 11 \\14 & 6 \\15 & 4 \\16 & 3 \\17 & 7 \\18 & 2 \\19 & 3\end{array}$
C)
$\begin{array}{r|r}\text { Number of } & \\\text { years of } & \text { } \\\text { education } & \text { Frequency } \\\hline 11 & 1 \\12 & 3 \\13 & 12 \\14 & 5 \\15 & 4 \\16 & 3 \\17 & 8 \\18 & 2 \\19 & 2\end{array}$

D)
$\begin{array}{r|r}\begin{array}{r}\text { Number of } \\\text { years of }\end{array} & \\\text { education } & \text { Frequency } \\\hline 12 & 3 \\13 & 11 \\14 & 5 \\15 & 4 \\16 & 3 \\17 & 8 \\18 & 2 \\19 & 3\end{array}$
