I have a population of n=5 scores 0, 6, 4, 3, 12
I need to compute mean and standard deviation for the population
u____ o_____
I need to find the z score for each of the population, and transform the original population into a new population of n= 5 scores with a mean of u= 100 and a standard deviation of o= 20.
original x = 0 z score ____ transformed x___
original x= 6 z score _____ transformed x____
original x= 4 z score ____ transformed x ____
original x= 3 z score ____ transformed x ____
original x= 12 z score____ transformed x ____

Solution Summary
The solution gives detailed steps on computing population mean and variance and transforming between two normal random variables.
Solution Preview
1. u=(0+6+4+3+12)/5=5
o=sqrt{[(0-5)^2+(6-5)^2+(4-5)^2+(3-5)^2+(12-5)^2]/(5)}=4
2. since z=(x-u)/o, so x=zo+u
original ...
