Answer:
B
Step-by-step explanation:
The ACT score was better since the z-score of the ACT is greater than the z-score of the SAT. Then the correct option is B.
<h3>What is a normal distribution?</h3>
It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.
The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.
The z-score is given as

In 1985, the average ACT score was 18 with a standard deviation of 6.
Also in 1985, the average SAT score was 500 with a standard deviation of 100.
Dr. Robertson took both tests in 1985 and scored a 26 on the ACT and a 620 on the SAT.
Then the z-score of the ACT will be

Then the z-score of the SAT will be

Then the ACT score was better since the z-score of the ACT is greater than the z-score of the SAT.
