Question 629355: A test measuring basic literacy skills in children is normally distributed, with � = 18 and σ = 5. How do I calculate the z score for each test score, example: a test socre of 11?

You can put this solution on YOUR website!
z = (x - mu)/(sigma)

z = (x - 18)/(5)

z = (11 - 18)/(5)

z = (-7)/(5)

z = -1.4
