Question

Set up a frequency distribution table and calculate the relative frequency for the following quiz scores that Matt achieved in his Algebra course: Matts Quiz Scores: 85, 88, 92, 71, 100, 78, 61, 61, 89, 99, 100, 65, 98, 85, 92, 79, 81, 85, 100, and 100. Use the following frequency intervals: 61 - 70 71 - 80 81 - 90 91 - 100 Calculate the variance and standard deviation for Matts quiz scores. Suggestion: set the problem up in steps within a table like the textbook illustrates. Patricks Average Sales: Monday exist4, 099 Tuesday exist6, 700 Wednesday exist0 Thursday exist10,000 Friday exist9,007 Saturday exist9, 776 Sunday exist0 Is it better for Patrick to earn 7.5% based on his average weekly sales, or a flat exist4,000 for the week?
