(click again to close the tab.) The February 2011 issue of Consumer Reports magazine provides the Overall Score ratings for exercise treadmills. There are two treadmill categories: nonfolding and folding. Here are the Overall Score ratings for these two types of treadmill: Folding Treadmills Folding Treadmill Data Non-Folding Treadmill Data 81 85 79 84 76 83 76 82 75 81 74 78 73 78 73 69 73 65 72 60 71 71 71 70 70 69 66 66 65 65 64 63 61 61 50 (1) We want to compare the these two distributions of data. It is important that we use Start License Dot Plot Frequency Diagram Relative Frequency Diagram to compare the distributions. (2) Create the side-by-side graphs mentioned in the first part (either by hand or with technology). (3) Describe and compare the important features of the distributions of the Overall Score ratings for the two types of treadmills.   (3) Suppose your friend is going to purchase a treadmill, but cannot decide whether to purchase a nonfolding or folding model. Regardless of the price, which type would you recommend for the highest quality. What evidence do you have to recommend one type over the other. Be specific.   (4) Turn in your side-by-side graphs next class. Points possible: 10 Unlimited attempts. https://www.myopenmath.com/course/showlicense.php?id=238945

(3) The distribution of both the variables is approximately normally distributed. This is because the frequency distribution is bell shaped for both variables
(3) The number of people who prefer folding treadmill data is much more than number of people who prefer non-folding treadmill data. Hence, I recommend that folding treadmill data has highest quality.
