Question 488453: A set of 50 data values has a mean of 41 and a variance of 36.
I. Find the standard score (z) for a data value = 24.
II. Find the probability of a data value > 24.
You can put this solution on YOUR website! A set of 50 data values has a mean of 41 and a variance of 36.
Note: the standard deviation = sqrt(36) = 6
I. Find the standard score (z) for a data value = 24.
z(24) = (24-41)/6 = -2.8333
==================================
II. Find the probability of a data value > 24.
P(x > 24) = P(z > -2.8333) = 0.9977
==================================
