Set up a frequency distribution table and calculate the relative

Question 2: (20Points)   a)    Set up a frequency distribution table and calculate the relative frequency for the following quiz scores that Matt achieved in his Algebra course: Matt’s Quiz Scores: 85, 88, 92, 79, 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   b)    Calculate the variance and standard deviation for Matt’s quiz scores.  Suggestion: set the problem up in steps within a table like the textbook illustrates.   Question 3: (10 Points) Patrick’s Average Sales:   Monday $4,099 Tuesday $6,900 Wednesday $0 Thursday$10,000 Friday $9,007 Saturday $9,766 Sunday $0   Is it better for Patrick to earn 7.5% based on his average daily sales or a flat $4,000 for the week?
