QuestionFind the proportion of SAT verbal scores between 400 and 600, given a mean of 500 and a standard deviation of 100.

Studdy Solution
Now, we need to find the proportion of scores between z400z_{400} and z600z_{600}. In a standard normal distribution, the proportion of scores between -1 and1 (i.e., within one standard deviation from the mean) is approximately0.6826.
So, the proportion of scores that fall between400 and600 according to the zz distribution is0.6826.
