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.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
