Solution:
Given the data below:
To determine the relative frequency, given that the class width is 5,
we have
[tex]\begin{gathered} score:\text{ 79 to 83} \\ relative\text{ frequency = }\frac{8}{19}=0.42 \\ score:84\text{ to 88} \\ relative\text{ frequency = }\frac{1}{9}=0.11 \\ score:89\text{ to 93} \\ relative\text{ frequency=}\frac{6}{19}=0.32 \\ score:94\text{ to 98} \\ relative\text{ frequency=}\frac{4}{19}=0.21\sqrt{\placeholder{⬚}} \end{gathered}[/tex]
Hence, we have
