What proportion of a normal distribution falls above a z-score of 2.10?
It is 0.017864
What proportion of a normal distribution falls above a z-score of 1.16?
Pr(Z > 1.16) = 0.123
What proportion of a normal distribution falls between z 1.16 and z 1.16?
0% of a normal (of any) distribution falls between z 1.16 and z 1.16. 1.16 - 1.16 = 0.
What proportion of the normal curve falls below a z score of 2.58?
Approx 0.995
What proportion of a normal distribution falls between z equals negative 1.16 and z equals positive 1.16?
1.16/z = -1.16/z * * * * * No! Pr(Z > 1.16) = 0.123 So Pr(-1.16 < Z < 1.16) = 1 - 2*0.123 = 1 - 0.246 = 0.754

0.50
What is the difference between the coefficient of simple determination and that of multiple determination?
The coefficient of simple determination tells the proportion of variance in one variable that can be accounted for (or explained) by variance in another variable. The coefficient of multiple determination is the Proportion of variance X and Y share with Z; or proportion of variance in Z that can be explained by X & Y.
What is the proportion of a normal distribution is located in the tail beyond a z score of z equals 1.00?
It is 0.158655, approx.
What proportion of a normal distribution is located between z equals -0.50 and z equals plus 0.50?
0.3829 approx.
