Solution: We have to find the Frequency and Relative frequency of the given data:
Frequency is the number of times a number occurs.
Relative Frequency is the number of times a number occurs divided by the total number of items.
Therefore, the frequency and relative frequency are calculated as below:
Number Frequency Relative Frequency
20 1 [tex]\frac{1}{31} \times 100 =3.2\%[/tex]
21 4 [tex]\frac{4}{31} \times 100 =12.9\%[/tex]
22 2 [tex]\frac{2}{31} \times 100 =6.5\%[/tex]
23 4 [tex]\frac{4}{31} \times 100 =12.9\%[/tex]
24 3 [tex]\frac{3}{31} \times 100 =9.7\%[/tex]
25 2 [tex]\frac{2}{31} \times 100 =6.5\%[/tex]
26 3 [tex]\frac{3}{31} \times 100 =9.7\%[/tex]
27 5 [tex]\frac{5}{31} \times 100 =16.1\%[/tex]
28 3 [tex]\frac{3}{31} \times 100 =9.7\%[/tex]
29 4 [tex]\frac{4}{31} \times 100 =12.9\%[/tex]
Total 31
