For Problems 33 -40: Below are the tree heights of 15 trees in a nature preserve [in ft): 11, 13, 21, 22, 26, 32, 35, 37, 37, 37, 40, 42, 48, 51, 55 33. Create a stem-and-leaf plot for these data. [4 points) 4 2$171 15 Key +317 : 37 34. Based on the stem-and-leaf plot, the distribution of the test scores appears to be: (2 points) A. Symmetric & unimodal B. Uniform C. Right-skewed D. Left-skewed 35. Calculate the 5-number summary for the tree heights. Remember to present the summary in the correct order. Show work where necessary. (4 points) 41: 11 37 155. 36. Calculate the lower limit for determining low outliers. (3 points) 41 - 12 : 16 -8 14 + 1-1.5(2-) 37. Are there any low outliers? If yes, list them. (1 point) 38. Calculate the upper limit for determining high outliers. (3 points) 41 4 15 ( 1012 ) 71. 39. Are there any high outliers? If yes, list them. (1 point) No 2Zap. Based on your analysis, the best measures of center and variability for the tree height data are (2 ppleits) D A. mean and IOR B. median and IOR C. median and standard deviation D. mean and standard deviation
