20010101uuuuu1-Sample t TestThis test uses the hypothesis test for a single unknown population mean when the populationstandard deviation is unknown. The 1-Sample t Test is applied to t-distribution.t = o – 0μσx n–1no : mean of sampleμ0 : assumed population meanxσn-1 : sample standard deviationn : size of samplePerform the following key operations from the statistical data list.3(TEST)c(T)b(1-Smpl)The following shows the meaning of each item in the case of list data specification.Data ............................ data typeμ .................................. population mean value test conditions (“Gμ0 ” specifies two-tail test, “<μ0” specifies lower one-tail test, “>μ0 ” specifiesupper one-tail test.)μ0 ................................. assumed population meanList .............................. list whose contents you want to use as data (List 1 to 20)Freq ............................. frequency (1 or List 1 to 20)Save Res ..................... list for storage of calculation results (None or List 1 to 20)Execute ....................... executes a calculation or draws a graphThe following shows the meaning of parameter data specification items that are differentfrom list data specification.o .................................. mean of samplexσ n-1 ............................. sample standard deviation (xσ n-1 > 0)n .................................. size of sample (positive integer)After setting all the parameters, align the cursor with [Execute] and then press one of thefunction keys shown below to perform the calculation or draw the graph.• 1(CALC) ...
