Hi,

Could you please explain how you found the answer for Z - 2.165. I tried to look it up using the standard normal distribution table but could not find the answer. Could you please advise how I can graph this on a TI-84 plus CE calculator. Thank you.

Answer to Problem 6TY
The area under the standard normal curves between z = -2.165 and z = -1.35 is 0.0733.
Explanation of Solution
Given info:
The mean and standard deviation of the standard normal distribution is 0 and 1.
Calculation:
Software procedure:
Step-by-step procedure to obtain the area using the MINITAB software:
• Choose Graph > Probability Distribution Plot choose View Probability > OK.
• From Distribution, choose "Normal' distribution.
• Click the Shaded Area tab.
• Choose X Value and Middle for the region of the curve to shade.
• Enter the X value 1 as-2.165 and X value 2 as -1.35.
• Click OK.
Output using the MINITAB software is given below:

From MINITAB output, it can be observe that the area under the standard normal curve between z = -2.165
and z = -1.35 is approximately 0.0733.
Thus, the area under the standard normal curve between z = -2.165 and z = -1.35 is 0.0733.
