1. For each of the given population would the score of X=50 be considered central score (near middle of distribution) or extreme score (far out in the tail of the distribution )?

a) μ=45 and σ=10
b) μ=40 and σ=2
c) μ=55 and σ=2
d) μ=60 and σ=20

2. Population consists of following N=5 scores: 0,6,4,3, and 12

a) Distinguish μ and σ for the population

b) Determine the z-score for each score in population

c) Transfer original population into the new population of N=5 scores with mean of μ=60 and a standard deviation of σ=8
