For each of the following population would a score of X=50 be considered a central score (near the middle of the distribution) or an 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. a population consists of the following N=5 scores:
0,6,4,3, and 12
a)compare μ and σ for the population
b)find the z-score for each score in the population
c)transfer the original population into a new population of N=5 scores with a mean of μ=60 and a standard deviation of σ=8
