Question

Refer to the following distribution:

Cost of textbooks Number
$25 up to $35 2
35 up to 45 5
45 up to 55 7
55 up to 65 20
65 up to 75 16
What is the relative class frequency for the $25 up to $35 class?

Answer 1

0.04

Step-by-step explanation:

Number of books = 2 + 5 + 7 + 20 + 16

Number of books = 50

Specific occurrences in $25 to $35 class = 2

Total items = 50

Relative frequency = Specific occurrences / Total items

Relative frequency = 2/50

Relative frequency = 0.04

So, the relative class frequency for the $25 up to $35 class is 0.04.
