Answer:

720

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
