b. a relative frequency distribution.

c. a cumulative frequency distribution.

d. construct a frequency distribution.

e. construct a frequency polygon for the data.

f. draw a cumulative frequency polygon.

Explanation / Answer

Sol)

a) Frequency Distribution

class interval of $4,000 with $12,000 as the lower limits of the first class)

we can calculate Relative freq using formula= (freq / total freq)b) Relative frequency distribution.

C) cumulative frequency distribution

d) construct a frequency distribution.

CIass Interval 12000-16000 16000-20000 20000-24000 24000-28000 28000-32000 32000-36000
