Computing the mean and standard deviation for the given data.
1.A population of scores has µ = 50 and s = 12. If you subtract five points from every score in the population, then the value for the new standard deviation will be
a.7
b.12
c.2.4
Insufficient information, cannot be determined
2. A population of N = 10 scores has µ = 50 and s = 5. What is the population variance?
a.The square root of 5
b.The square root of 50
c.10
d.25
