Here is the z-score: Please provide a graph (normal distribution curve for this z-score). Please provide a title also for the graph that you will create.
Here is the data in my answer in case you need:
Mean = 6.4
Standard deviation = 1.28
Average hours (X) = 4, 5, 6, 7, 8
The topic of my normal probability distribution is (The average number of hours spent studying in a week by 30 students).
1.) 4 X - H Z = SD 4 - 6.4 Z= 1.28 -2.4 Z= 1.28 Z= -1.88 2.)5 X - Z = SD 5 - 6.4 Z = 1.28 -1.4 Z = 1.28 Z = -1.09 3.) 6 X- H Z= SD 6 - 6.4 ZE 1.28 -0.4 Z= 1.28 Z= -0.31 4.)7 X - Z = SD 7 - 6.4 Z = 1.28 0.6 Z= 1,28 Z = 0.47 5.) 8 X - L Z= SD 8 - 6.4 Z = 1.28 1.6 1.28 Z = 1.25Given the data above, find the equivalent z-score of the random variables and graph it in the normal distribution.
