An environmental biologist recorded the 20 24 22 20 numbers of snail eggs in the first clutch (group) laid at different temperatures, as shown in the histograms to the left. At 22 C, the snails laid a mean of 49 eggs.At 25C, they laid a mean of 31 eggs. Which statement best compares the standard deviations of the numbers of eggs? 25 50 75 100 125 150 175 200 225 Number of eggs in first clutch at 22 C A) Both sets vary too much to have a valid 28 26 24 standard deviation. The standard deviation is greater when the first clutch is at 22 C. C) The standard deviation is greater when the first clutch is at 25 C. D) The standard deviations at both temperatures are about the same. 25 50 75 100 125 150 175 200 225 Number of eggs in first clutch at 25 C B) Number of snails Number of snails

Question
An environmental biologist recorded the 20 24 numbers of snail eggs in the first clutch (group) 22 20 18 laid at different temperatures, as shown in the 16 14 histograms to the left. At 22 C, the snails laid a 12 10 mean of 49 eggs.At 25C, they laid a mean of 31 eggs. Which statement best compares the standard deviations of the numbers of eggs? 25 50 75 100 125 150 175 200 225 Number of eggs in first clutch at 22° C A) Both sets vary too much to have a valid 28 26 standard deviation. 24 B) The standard deviation is greater when the 22 20 first clutch is at 22 C. 18 16 C) The standard deviation is greater when the 14 12 first clutch is at 25 C. 10 8. D) The standard deviations at both temperatures are about the same. 25 50 75 100 125 150 175 200 225 Number of eggs in first clutch at 25° C Number of snails Number of snails
