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.
