I Calculations Using the TEST Command Important! • The following operations cannot be performed on the fx-7400GII. You can use special functions in the RUN • MAT mode or PRGM mode to perform calculations that are the same as the STAT mode Z Test, t Test, and other test calculations (page 6-22). Example To determine the z score and p-value when a one-sample Z test is performed under the conditions below: test condition (ƫcondition) x ƫ0*, assumed population mean ƫ0 = 0, population standard deviation Ʊ = 1, sample mean M = 1, number of samples n = 2 * "ƫ condition x ƫ0" can be specified by entering 0 as the initial argument of the one-sample Z test command "OneSampleZTest". 1. From the Main Menu, enter the RUN • MAT mode. 2. Perform the following key operation. *(STAT)(E)(TEST)(Z) (1-S)??@@A U ))) (LIST)(List) (Ans)U The following calculation results are displayed as ListAns elements 1 through 4. 1: z score 2: p-value 3: M 4: n • For details about the function of the supported TEST command and their syntax, see "Using the TEST Command to Execute a Command in a Program" (page 8-32). 5. Tests Important! • Test calculations cannot be performed on the fx-7400GII. The Z Test provides a variety of different standardization-based tests. They make it possible to test whether or not a sample accurately represents the population when the standard deviation of a population (such as the entire population of a country) is known from previous tests. Z testing is used for market research and public opinion research, that need to be performed repeatedly. 6-22
