Solution:- The probability that the average length of a randomly selected bundled of steel rods is between 212.9 and 213.2 is 0.06.
Mean = 212.2, S.D = 2.1, n = 17
x1 = 212.9
x2 = 213.2
By applying normal distribution:-
z1 = 1.374
z2 = 1.963
P( 1.374 < z < 1.963) = P(z > 1.374) - P(z > 1.963)
P( 1.374 < z < 1.963) = 0.085 - 0.025
P( 1.374 < z < 1.963) = 0.06.
