Question

If your zst is 4 your usl is 50 and standard deviation is 2 what is your mean

Answer 1

Answer:

42

Step-by-step explanation:

Given If your zst is 4 your usl is 50 and standard deviation is 2 what is your mean

We know that z = x – mean / standard deviation

So we get z x standard deviation = x – mean

           X = z x std deviation + mean

         Mean = x – (std deviation x z)

         Mean = 50 – (2 x 4)

        Mean = 50 – 8

        Mean = 42
