Five-way stem splitting Sometimes, the variability in a data set is so small that splitting stems in two doesn%u2019t produce a stemplot that shows the shape of the distribution well. We can often solve this problem by splitting the stem into five parts, each consisting of two leaf values: 0 and 1, 2 and 3, 4 and 5, and so on. See Your Turn 1.4 and Exercise 20 for an example.Here are the weights, in ounces, of 36 navel oranges selected from a large shipment to a grocery store:5.7 5.4 5.8 5.3 4.6 4.9 5.6 5.3 5.5 5.5 5.4 5.85.3 5.5 5.5 5.4 5.8 5.9 5.4 5.1 5.0 5.5 5.7 4.95.0 5.3 5.1 5.2 5.7 5.6 5.8 4.5 5.2 5.4 5.7 5.6Make a stemplot of the data by splitting stems into five parts. Describe the shape of the distribution.22. Truncating and rounding Sometimes, the values in a data set have too many digits for making a stemplot. We can often solve this problem by rounding or by truncating (deleting the final digit(s) of) each data value. See Exercises 13 and 20, respectively, for examples.One way to measure the effectiveness of baseball pitchers is to use their earned run average,which measures how many earned runs opposing teams score, on average, every nine innings pitched. The overall earned run average for all pitchers in the major leagues in 2019 was 4.49. Here are the earned run averages for all 20 players who pitched at least 15 innings for the World Champion Washington Nationals in 2019:503.32 3.25 2.92 3.85 4.50 4.05 4.54 4.86 3.91 6.365.48 3.30 6.23 4.05 6.66 1.44 4.71 5.14 10.13 4.02(a) Truncate (delete) the hundredths place of each data value and make a stemplot, using the ones digit as the stem and the tenths digit as the leaf.(b) Make another stemplot of the data by rounding each data value to the nearest tenth.(c) How do the shapes of the graphs in (a) and (b) compare?Recycle and Review23.
