Biologists Know That Bats Have Different Flight Characteristics

Essay

Biologists know that bats have different flight characteristics. Some bats exhibit fast, straight, and long flights; others are moderately slow, and highly maneuverable. The flight capabilities of bats are presumably a function of (a) the characteristics of the bat wings, and (b) the laws of physics. The data presented below are wing weights in grams for certain species of bats from Nicaragua and Costa Rica. Two categories of bat species are represented: fruit-eaters and insect-eaters.
Fruit eaters:
9.9, 11.5, 47.0, 59.6, 18.2, 22.1, 22.9, 15.0, 15.4, 13.3, 38.3, 42.2, 114.3, 105.4, 80.9
Insect eaters:
23.8, 16.1, 4.2, 3.9, 7.5, 3.5, 3.9
(a)Construct two dotplots that will allow you to easily compare the distributions of the wing weights for the two categories of bats, fruit-eaters and insect-eaters.
(b)Write a short paragraph describing the features of the two plots; what do these plots tell you about the differences in wing weight for fruit- and insect-eaters?
