Math Problem Statement
Find the range, variance, and standard deviation for the given sample data, if possible. If the measures of variation can be obtained for these values, do the results make sense? Biologists conducted experiments to determine whether a deficiency of carbon dioxide in the soil affects the phenotypes of peas. Listed below are the phenotype codes, where 1equals smooth-yellow, 2equals smooth-green, 3equals wrinkled yellow, and 4equals wrinkled-green. 1 1 2 2 3 2 4 1 2 2 2 2 1 2 2 3 1 2 2 2
