Question

Question 2: (20 Points)

Set up a frequency distribution table and calculate the relative frequency for the following quiz scores that Pat achieved in his Algebra course:

Matt’s Quiz Scores: 84, 88, 92, 80, 100, 78, 61, 60, 79, 99, 100, 69, 98, 85, 92, 79, 81, 85, 100, and 100.

Use the following frequency intervals:

60 – 70

70 – 80

80 – 90

90 – 100

Calculate the variance and standard deviation for Pat’s quiz scores.
Suggestion: set the problem up in steps within a table like the textbook illustrates.

Question 3: (10 Points)

Mark’s Average Sales:

Monday \$4,199

Tuesday \$6,900

Wednesday \$0

Thursday \$11,000
