A university plans to award scholarships to students whose scores are in the top 9 % . What is the minimum score required for the scholarship? TablesKeypad we have found the value-z =-1.34, such that the area to the left of-z is approximately 0.09. Since the standard normal curve is symmetric and centered at zero, the z-value of the minimum score required for the scholarship is z 1.34. Substitute the known values of the standard score z, the mean μ, and the standard deviation σ into the standard score formula below. x-μ
