$\begin{array}{cccc}{Class} & {Frequency} & {Relative Frequency} &{Percent\ Frequency}\ \\ {12-14} & {2} & {0.05} & {5\%}& {15-17} & {8} & {0.200}&{20\%}& {18-20} & {11} & {0.275} & {27.5\%}& {21-23} & {10} & {0.250} &{25\%}& {24-26} & {9} & {0.225}&{22.5\%} & {Total} & {40} & {1} & {100\%}\ \end{array}$

Step-by-step explanation:

Required

Complete the table.

First, group the data according to the class.

So, we have:

12-14:- 14 12 --- Frequency is 2

15 - 17:- 16 16 16 16 16 17 16 15 --- Frequency is 8

18 - 20:- 19 19 19 18 19 18 20 20 19 20 20 --- Frequency is 11

21 - 23:- 21 23 21 22 21 23 23 22 22 22 --- Frequency is 10

24 - 26:- 25 24 24 25  25  24 26  24  24 --- Frequency is 9

Next, fill the class frequency column

$\begin{array}{cc}{Class} & {Frequency} \ \\ {12-14} & {2} & {15-17} & {8} & {18-20} & {11} & {21-23} & {10} & {24-26} & {9}\ \end{array}$

Relative frequency is calculated by dividing each frequency by the total frequency (40).

So, we have:

$\begin{array}{ccc}{Class} & {Frequency} & {Relative Frequency}\ \\ {12-14} & {2} & {0.05} & {15-17} & {8} & {0.200}& {18-20} & {11} & {0.275} & {21-23} & {10} & {0.250} & {24-26} & {9} & {0.225}\ \end{array}$

The percent frequency is calculated by multiplying the relative frequency by 100%.

So, we have:

$\begin{array}{cccc}{Class} & {Frequency} & {Relative Frequency} &{Percent\ Frequency}\ \\ {12-14} & {2} & {0.05} & {5\%}& {15-17} & {8} & {0.200}&{20\%}& {18-20} & {11} & {0.275} & {27.5\%}& {21-23} & {10} & {0.250} &{25\%}& {24-26} & {9} & {0.225}&{22.5\%} & {Total} & {40} & {1} & {100\%}\ \end{array}$
