Determine the population mean for the population

Reference no: EM13111989

1. The sample has mean of M=40 and standard deviation of s=4 determine the z-score for each of given X values from the sample.

X=44
X=42
X=48
X=28
X=50
X=46

2. Score that is 6 points below mean corresponds to z-score of z=-2.00. Determine the population standard deviation?

3. For the population with standard deviation of σ =10 a score of x=44 corresponds to z= -0.50. Determine the population mean?
