Question

For each of the following z-score locations, use the Standard Normal Distribution tool to determine whether the body is on the right or left side of the line and to find the proportion in the body.

For z= 2.20, the body is to the ___________, and the proportion in the body is p=__________.

For z= -0.60, the body is to the ___________, and the proportion in the body is p=__________.

For z= -1.1, the body is to the ___________, and the proportion in the body is p=__________.

For z= -0.70, the body is to the ___________, and the proportion in the body is p=__________.

Answer 1

i) For Z = 2.20, the body is to the left side

P(Z < 2.20) = 0.9861

and the proportion in the body is p = 0.9861

ii) For Z = -0.60, the body is to the right side

P(Z > -0.60) = P(Z < 0.60) = 0.7257

and the proportion in the body is p = 0.7257

iii) For Z = -1.1, the body is to the right side

P(Z > -1.1) = P(Z < 1.1) = 0.8643

and the proportion in the body is p = 0.8643

iv) For Z = -0.70, the body is to the right side

P(Z > -0.70) = P(Z < 0.70) = 0.7580

and the proportion in the body is p = 0.7580
