listed are 2008-2009 cost of out-of-state undergraduate tuition and fees (in dollars) at the 34 AAU public universities. For this data construct:

a. a frequency distribution (use a class interval of $4,000 with $12,000 as the lower limits of the first class)

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.

Solution

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.
