The following shows the meaning of each item in the case of list data specification.

Data ............................

data type

C-Level ........................

confidence level (0 <C-Level < 1)

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 data of sample 1

 

(List 1 to 20)

List(2) ..........................

list whose contents you want to use as data of sample 2

 

(List 1 to 20)

Freq(1) ........................

frequency of sample 1 (1 or List 1 to 20)

Freq(2) ........................

frequency of sample 2 (1 or List 1 to 20)

Save Res .....................

list for storage of calculation results (None or List 1 to 20)

Execute .......................

executes a calculation

The following shows the meaning of parameter data specification items that are different from list data specification.

o1 .................................

mean of sample 1

n1 .................................

size (positive integer) of sample 1

o2 .................................

mean of sample 2

n2 .................................

size (positive integer) of sample 2

After setting all the parameters, align the cursor with [Execute] and then press the function key shown below to perform the calculation.

• 1(CALC) ... Performs the calculation. Calculation Result Output Example

Left ..............................

interval lower limit (left edge)

Right ............................

interval upper limit (right edge)

o1 .................................

mean of sample 1

o2 .................................

mean of sample 2

x1σn-1 ............................
