We will expand Example 1.22, Page 66 to include (in addition to the top 10%) the top 5%,15%, and 20%.
Create a JMP data table that looks like the following:
Use the calculator to create the following additional columns (see intructions below):
Compare the x column with the answer of Example 1.22.
These additional columns were created using the JMP calculator as follows:
You can download the JMP file here.
OPTIONAL:
You could have done this problem a shorter way by programing the column x directly in term of the column Top Fraction, that is, without creating the intermediate columns Bottom Fraction and z-score. Do you want to try?
Hint:
