The following self$-$contained, stand$-$alone SAS code performs the following steps: $(1)$ It reads

data into SAS; $(2)$ For a given variable, it performs an imputation or missing values using the

average of observed values for that variable; and $(3)$ It produces descriptive statistics of the

resulting variable after imputation, for a subset of the data. Fill the blanks in the code with the

missing variables$/$commands $($one variable$/$command per space allocated$).[17$ points$]$
