Answer:
The proportion of individuals score at most 74 points on this test is 70%.
Step-by-step explanation:
The complete question is:
Suppose that the scores on a reading ability test are normally distributed with a mean of 70 and a standard deviation of 8. What proportion of individuals score at most 74 points on this test? Round your answer to at least four decimal places.
Solution:
Let <em>X</em> represent the scores on a reading ability test.
It is provided that
.
Compute the probability that an individuals score is at most 74 points on this test as follows:
![P(X\leq 74)=P(\frac{X-\mu}{\sigma}\leq \frac{74-70}{8})](https://tex.z-dn.net/?f=P%28X%5Cleq%2074%29%3DP%28%5Cfrac%7BX-%5Cmu%7D%7B%5Csigma%7D%5Cleq%20%5Cfrac%7B74-70%7D%7B8%7D%29)
![=P(Z](https://tex.z-dn.net/?f=%3DP%28Z%3C0.50%29%5C%5C%3D0.69146%5C%5C%5Capprox%200.70)
Thus, the proportion of individuals score at most 74 points on this test is 70%.
