The mean of a set of credit scores is and. Which credit score is within a z-score of 3.3?

720

Step-by-step explanation:

The mean of a set of credit scores is u=690 and o=14.

mean = 690 and standard deviation SD = 14

We use z - score formula

z = 3.3 given

Plug in the values and find out x

Multiply 14 on both sides

46.2 = x - 690

Now add 690 on both sides

x = 736.2

Credit score is 720 that comes under 736.2
