The ABC Manufacturing Corporation produces
steel rods. Due to manufacturing defects, there is
some small variation in the lengths of the rods.
The lengths of the rods have a Normal distribution
with mean
cm. and standard deviation
cm. Suppose one steel rod is randomly
selected from a batch and measured.
For each problem #1 – 3, show any relevant z-score calculation, draw a normal curve, label the mean
of the distribution, and shade in the region that illustrates the area representing the given probability.
1. Find the probability that a randomly-selected steel rod has a length less than 24.90 cm. (3 pts)
