The length of metallic strips produced by a machine has mean 100 cm and variance 2.25 cm. Only strips with length between 98 and 103 cm are acceptable. What proportion of strips will be acceptable? You may assume that the length of a strip has a Normal Distribution.

To solve this problem, we'll use the properties of the normal distribution. Given that the length of metallic strips follows a normal distribution with a mean of 100 cm and a variance of 2.25 cm², we want to find the proportion of strips that fall within the acceptable range of 98 to 103 cm.

First, let's standardize the distribution by converting it to a standard normal distribution with mean 0 and variance 1. This is achieved by using _____ __________ _________ _______ _________ ____.
