Question

Step 1: A study of 584 longleaf pine trees in the Wade Tract in Thomas County, Georgia is described in Example 6.1. For each tree in the tract, the researchers measured the diameter at breast height (DBH). This is the diameter of the tree at 4.5 feet and the units are centimeters (cm) Only trees with DBH greater than 1.5 cm were sampled Here are the diameters of a random sample of 40 of these trees: 10.5 13.3 26.0 8.3 52.2 9.2 26.1 17.6 40.5 31.8 47.2 11.4 2.7 69.3 44.4 6.9 35.7 5.4 44.2 2.2 4.3 7.8 38.1 2.2 11.4 51.5 4.9 39.7 32.6 51.8 43.6 2.3 44.6 31.5 40.3 22.3 3.3 37,5 29 27.9 Data Set Use a histogram or stemplot and a boxplot to examine the distribution of DBHs. Include a Normal quantile plot if you have the necessary software Write a careful description of the distribution. O The distribution is somewhat left-skewed, with two peaks and no apparent outliers. O The distribution is right-skewed with two peaks and one outlier. O There are no special deviations from Normality. O The distribution is right-skewed with several high outliers.
