Home --> Departments --> Mathematics --> CASIO Graphics Calculator --> Statistics --> The Normal Distribution

In AS 2.6 you must show the calculation for the Z value. You must also write a correct Probability sentence. Once you have done this then you can use the graphics calculator to calculate the Probability without needing to use a Table.

Follow the arrow Menu --> STAT --> F5(DIST) --> F1(NORM) --> F2(Ncd)

By now you should have sketched a simple diagram with the required area shaded.

__**YOU MUST ENTER ACTUAL MEASURMENTS AND NOT STANDARISED MEASURMENTS**__
For "Lower" enter the lower boundary(number) - the extreme right of the shaded area - of your shaded area, if the lower boundary is "open" then enter a number that is significantly smaller than the measurment required --> EXE For "Upper" enter the upper boundary(number) - the extreme left of the shaded area - of your shaded area, if the upper boundary is "open" then enter a number that is significantly higher than the measurment required --> EXE Enter the standard deviation given in your question --> EXE Enter the mean given in your question --> EXE --> EXE
