The score will be
The z-score of x= –, if it is standard deviations to the right of the mean?
By using the score it can be calculated by how many standard deviations (), the value of x will lie down (left) or overhead (right) the mean () of the distribution. Since it is delivered that the z-score is standard deviations to the right of the mean for x=-.
