Recently a study of fans attending the new york mets baseball games was conducted and 500 fans were surveyed. in forming a frequ

Misha Larkins [42]

Relative frequency is the value assigned to each class in the proportion of the total data set that belongs in the class.

Relative frequency formula is :

$\frac{class-Frequency}{Total- observations}$ --------------------(1)

So for class 0 to 5 miles we have 247 fans. So this class frequency is 247.

Total fans surveyed is 500

So plug these values in relative frequency formula given by (1)

relative frequency = $\frac{247}{500}$

On simplifying we get

relative frequency = 0.494

So choice (c) 0.494 is the right answer
