Blocking refers to the idea that the variability in a variable can be reduced by segmenting the data by some other variable. The data in the accompanying table represent the recumbent length (in centimeters) of a sample of 10 males and 10 females who are 40 months of age. Complete parts (a) through (d). E Click the icon to view the data table. (a) Determine the standard deviation of recumbent length for all 20 observations. cm (Round to two decimal places as needed.)
