Three classes at Larry's school started growing bean plants on the same day. Ten plants were randomly selected from each class and their heights, in centimeters, were recorded below. Plant Height (in centimeters) Average Horticulture Class 10 12 15 11 10 10 10 12 13 12 11.5 Biology Class 10 15 9 10 16 16 11 14 9 14 12.4 Earth Science 9 14 11 15 16 8 9 11 13 13 11.9 Class Using Larry's data, what would be a good estimate of the height of the entire population of bean plants is? 11.9 cm 12.4 cm 11.2 cm The population mean cannot be estimated without knowing the heights of ALL the plants
