Question

Consider the following frequency distribution:

Class Frequency
10 up to 20 12
20 up to 30 15
30 up to 40 25
40 up to 50 4
a. Construct a relative frequency distribution. (Round your answers to 3 decimal places.)
Class Relative Frequency
10 up to 20 ______
20 up to 30 ______
30 up to 40 ______
40 up to 50 ______
Total _________

Answer 1

Relative frequency

0.214

0.268

0.446

0.071

Total 1

Explanation:

The relative frequency is computed by dividing the individual frequencies to the sum of frequencies.

sum of frequencies=12+15+25+4=56

Class Relative Frequency

10-20 12/56=0.214

20-30 15/56=0.268

30-40 25/56=0.446

40-50 4/56=0.071

Total 12/56+15/56+25/56+4/56=56/56=1
