1. For sample of M=85, a score of X=90 corresponds to z=0.50 determine the sample of standard deviation?

2. In the population of exam scores scores if x=88 corresponds to z=+2.00 and a score of x=79 and corresponds to z=-1.00 determine the mean and standard deviation for population. Draw distribution and locate two scores on the sketch.

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

a) Calculate μ and σ for the population

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

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