Below are the heights (in inches) of a sample of football players. Graph the boxplot and find the values for each of the quartiles and outlier(s), if they exist. (10 points for total) Students use the data below to calculate: 85 83 79 55 70 775 89 76 28. Smallest value= Q1= Q2= Q3= Largest value= 87 88 88 85 86 Outlier(s) Draw the Boxplot inside the box and label all values:
1. The two plots have similar distrubutions. Are the distrubutions skewed left, approximtly symmetric, or skewed right? 2. Which is greater, the mean or the median, within each plot? Why does this make snese, gicen the type of distrubution you identified in the first part? 3. The population has drastically declined over recent years. Does the data show a difference in bee prefrence towards high quality hives versus how quality hives? Usse statistical evidennce to support your response.
