a) For the entire school, which was more popular, water slides or roller skating? (1 point)

THE ANSWER FOR A IS: ROLLER SKATING

The relative frequency of an event is the proportion of the total no. of a result under which a defined event occurred with respect to the whole actual event.

So, from the given table:

Roller staking is more popular because it has a higher amount of results.

[tex]\mathbf{\implies \dfrac{x}{100}\times 0.20 = 0.14}[/tex]

[tex]\mathbf{\implies0.20x = 14}[/tex]

[tex]\mathbf{\implies x = 70\%}[/tex]

The percentage of 8th graders that want to go to the water is 70%

c.
