For a population with μ=100 and σ=10, convert a score of 110 to a z‐score For a population with μ=100 and σ=10, convert a score of 85 to a z‐score For a population with μ=19 and σ=2.4, convert a score of 18 to a z‐score For a sample with M=100 and s=20, convert a score of 90 to a z‐score For a sample with M=525 and s=60, convert a score of 410 to a z‐score For a population with μ=100 and σ=10, what score corresponds to a z‐score of ‐2? For a population with μ=40 and σ=5, what score corresponds to a z‐score of +1.5? For a sample with M=92 and s=7, what score corresponds to a z‐score of ‐1.2? For a sample with M=2 and s=4, what score corresponds to a z‐score of ‐3? For a sample with M=600 and s=3, what score corresponds to a z‐score of +1.5? If z=+1.0, X=55 and σ=5, what is the population mean? If z=‐1.6, X=92 and σ=15, what is the population mean? If z=+2.5, X=16 and s=2, what is the sample mean? If the population mean μ=100, and a value of X=104 corresponds to a z‐score of +1.2, what is the value of the standard deviation σ? 15. If the sample mean M=54, and a value of X=50 corresponds to a z‐score of ‐4, then what is the value of the standard deviation s? 16. A population contains 5 scores: 1, 4, 5, 8, 12. Convert the number 8 to a z‐score.
