Given that the mean weight of a group of dogs

       μ = 38 pounds

Let 'x' be the weight of dogs

Let 'x' be the random variable in normal distribution

Given that z-score is zero

Step(ii):-

we know that the z-score

            ⇒  

            ⇒ 0 = x-38

           ⇒  x-38 = 0

          ⇒   x =38
