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, 3equalswrinkled ​yellow, and 4 equals​wrinkled-green.

Can the range of the sample data be obtained for these​ values? Choose the correct answer below​ and, if​ necessary, fill in the answer box within your choice.
A. The standard deviation of the sample data is nothing. ​(Round to one decimal place as​ needed.)
B. The standard deviation of the sample data cannot be calculated. Can the variance of the sample data be obtained for these​ values?

Choose the correct answer below​ and, if​ necessary, fill in the answer box within your choice.
A. The variance of the sample data is nothing. ​(Round to one decimal place as​ needed.)
B. The variance of the sample data cannot be calculated.

Do the results make​sense?
A. The measures of variation do not make sense because the standard deviation cannot be greater than the variance.
B. While the measures of variation can be​ found, they do not make sense because the data are​ nominal; they​ don't measure or count anything.
C. The measures of variation make sense because the data is​ numeric, so the spread between the values is meaningful.
D. It makes sense that the measures of variation cannot be calculated because there is not a large enough sample size to calculate the measures of variation.
