We find a sample of people and we weigh each person. The distribution of their weights is positively skewed with a mean of 157 and a standard deviation of 47. If this distribution is transformed into z-scores, what will be the resulting shape, mean, and standard deviation of the new distribution? For a population with µ = 75 and σ = 10 find the z-score corresponding to the following raw scores X = 70 X = 77 X = 75
