The mean of a set of credit scores is 690 and 14. which credit score is within a z-score of 3.3?
634
640
720
750

C. 720.

Step-by-step explanation:

We have been given that the mean of a set of credit scores is 690 and standard deviation is 14.

To find the credit score that is within a z-score of 3.3 we will use z-score formula.

, where,

,

,

,

.

Upon substituting our given values in above formula we will get,

Let us multiply both sides of our equation by 14.

Let us add 690 to both sides of our equation.

Upon looking at our given values we can see that credit score 720 is within a z-score of 3.3, while 750 is above our given z-score, therefore, option C is the correct choice.
