On Stаt Key (lоck5stаt.cоm) yоu cаn find a data set titled "US States - 3e (Physical Activity by Region) under the descriptive statistics area, one quantitative and one categorical variable. When you use the drop down menu to find the data set be sure it is the 3e (3rd edition data set) and be sure it says physical activity by region. For each state researchers recorded the region of the country the state was in, and also recorded the percentage of adults in that state who get 150 minutes of more of aerobic exercise per week. The regions are NE = Northeast, MW = Midwest, S = South, W = west. Once you open the data set, click on boxplot to view the comparative boxplot for the data set. Then, answer the questions below. Blank 1) Are there any outliers? If so, for which region(s)? Blank 2) Based on what you see, would it be most accurate to say there is no relationship between region and activity level, a weak relationship, or a strong relationship? Blank 3) Overall, which region has the largest percentage of adults getting 150 minutes or more of aerobic exercise per week? Blank 4) Estimate the median for the S (south) region.
