In Exercises 520, find the range, variance, and standard deviation for the given sampledata. Include appropriate units (such as minutes) in your results. (The same data wereused in Section 3-2 where we found measures of center. Here we find measures of variation.)Then answer the given questions. Phenotypes of Peas Biologists conducted experiments to determine whether a deficiencyof carbon dioxide in the soil affects the phenotypes of peas. Listed below are the phenotypecodes, where 1 = smooth@ yellow, 2 = smooth@green, 3 = wrinkled@yellow, and4 = wrinkled@green. Can the measures of center be obtained for these values? Do the resultsmake sense?2 1 1 1 1 1 1 4 1 2 2 1 2 3 3 2 3 1 3 1 3 1 3 2 2
