A population of scores with µ (mean) = 73 and σ (SD)= 20 is standardized to create a new population with µ = 50 and σ = 10. What is the new value for each of the following scores from the original population?

Scores to transform: 63, 65, 77, 83

Thank you for the opportunity to help you with your question!

for 63, z = (X - µ)/σ = ( 63 - 73)/20 = -10/20 = -0.5X= µ + zσ = 50 + (-0.5)(10) = 50 -5 = 45for 65, z = (X - µ)/σ = (65-73)/20 = -8/20 X= µ + zσ = 50 + (-8/20)(10) = 50 -4 = 46for 77, z = (X - µ)/σ = (77-73)/20 = 4/20X= µ + zσ = 50 + (4/20)(10) = 52for 83, z = (X - µ)/σ = (83 -73)/20 = 10/20 = 0.5X= µ + zσ = 50 +(0.5)(10) = 55You can use my promo code : Ravi S and get $10 free :)
