Discussion Assignment #7
1. If a distribution is normal with μ = 60 and σ = 15, what is the z-score of 75?

The formula for calculating the z-score of any value is given by: Z = (X - μ)/ σ where X is the experimental result, μ is the mean value, and σ is the standard deviation. Consequently, if a distribution is normal with μ = 60 and σ = 15, the z-score of 75 is going to be ((75 – 60)/15) = 1. On the other hand, if a distribution is normal with μ = 60 and σ = 15, the z-score of 40 is going to be ((40 – 60)/15) = -1.3333. The norm...
