Given tip, T = $2.00 + (0.1 X C)
where C = cost of meal
Mean of cost of meals, M = $9.00
Standard deviation of meal, Sm = $3.00
If C = M,
Mean of tips Mt = $2.00 + (0.1 X $9.00)
Mt = $2.90, mean of tips
Standard deviation of tips, St = square root of mean of tips
St = ($2.90)^0.5
St = $1.70, standard deviation of tips
Therefore, mean of tips = $2.90 and standard deviation of tips = $1.70
