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

        Relative frequency

        0.214

        0.268

        0.446  

        0.071

Total  1

Step-by-step 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

i used to know how to do this in 7th but i forget easily
