a) greater than 50 atlas tires
z = (x - µ)/σ = (50 - 20.42)/14.24464 = 2.08
P (z > 50) = 0.0189
b) fewer than 30 atlas tires
z = (x - µ)/σ = (30 - 20.42)/14.24464 = 0.67
P (z < 30) = 0.7494
c) between 40 atlas tires and 80 atlas tires
z = (x - µ)/σ = (40 - 20.42)/14.24464 = 1.37
P (z = 40) = 0.9154
z = (x - µ)/σ = (80 - 20.42)/14.24464 = 4.18
P (z = 80) = 1.0000
Required probability = 1.0000 - 0.9154 = 0.0845
