Question 923310: A normally-distributed population has a mean μ = 74 and a standard deviation σ = 11. For a set of samples of size 8 taken from this population, what is the z-value for the proportion of the sample means that will be greater than 80? ( Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! samples of size 8
mean μ = 74 and a standard deviation σ = 11
t(80) = (80-74)/(11/sqrt(8)) = 1.5428
