Question:
A farmer wonders if his crops grow better in sun or in shade. He measures the amount of fruit gathered from a sample of 50 trees growing in full sun and from a sample of 50 trees growing in mostly shade. The five-number summaries, (minimum, 01, median, Q3, maximum), follow:
Amount of fruit gathered from sunny trees: (10.8, 13.3, 22.1, 58.1, 100) bushels
Amount of fruit gathered from shady trees: (10.9, 18.5, 29.3, 61.5, 127) bushels
a. On the same set of axes, create a boxplot for each type of tree. Compare the center, shape, spread, and outliers of amount of fruit from sunny trees to the amount from shady trees.
b. The farmer wants to summarize the amount of fruit from each type of orchard with a mean and standard deviation. Is that appropriate? Explain.
