a$)$ Use mean$($scores$)$ to compute the average of the data. Store the expression in the variable

avg$\_$score.

b$)$ Using comparison operators, write the R expression for scores less than or equal to the

mean of the data. Store the expression in the variable below$\_$avg.

c$)$ Using comparison operators, write the R expression for scores greater than the mean of the

data. Store the expression in the variable above$\_$avg.

d$)$ Using the sum function, write the R expression for the number of scores less than or equal

to the average of the data. Store the expression in the variable count$\_$below$\_$avg.

e$)$ Using the sum function, write the R expression for the number of scores greater than the

average of the data. Store the expression in the variable count$\_$above$\_$avg
