6-5-5 Tests u 2-Sample Z Test This test is used when the standard deviations for two populations are known to test the hypothesis. The 2-Sample Z Test is applied to the normal distribution. Z = o1 - o2 σn112+ σ22 n2 o1 : mean of sample 1 o2 : mean of sample 2 σ1 : population standard deviation of sample 1 σ2 : population standard deviation of sample 2 n1 : size of sample 1 n2 : size of sample 2 Perform the following key operations from the statistical data list. 3(TEST) 1(Z) 2(2-S) The following shows the meaning of each item in the case of list data specification. Data data type µ1 population mean value test conditions ("G µ2" specifies two- tail test, "< µ2" specifies one-tail test where sample 1 is smaller than sample 2, "> µ2" specifies one-tail test where sample 1 is greater than sample 2.) σ1 population standard deviation of sample 1 (σ1 > 0) σ2 population standard deviation of sample 2 (σ2 > 0) List(1 list whose contents you want to use as sample 1 data (List 1 to 26) List(2 list whose contents you want to use as sample 2 data (List 1 to 26) Freq(1 frequency of sample 1 (1 or List 1 to 26) Freq(2 frequency of sample 2 (1 or List 1 to 26) Save Res list for storage of calculation results (None or List 1 to 26) Execute executes a calculation or draws a graph 20050401
