Question 2: (20Points)<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

a) Set up a frequencydistribution table and calculate the relative frequency for the following quizscores that Matt achieved in his Algebra course:

Use the following frequency intervals:

60 – 70

70 – 80

80 - 90
