The normalt command will use the Z test to test the mean of data. You need to provide the command with the following arguments:
The normalt command will return the result of a Z test. It will return 0 if the test fails, 1 if the test succeeds, and it will display a summary of the test.
If you enter
you will get
*** TEST RESULT 0 *** Summary Z-Test null hypothesis H0 mu1=mu2, alt. hyp. H1 mu1!=mu2. Test returns 0 if probability to observe data is less than 0.1 (null hyp. mu1=mu2 rejected with less than alpha probability error) Test returns 1 otherwise (can not reject null hypothesis) Data mean mu1=10, population mean mu2=0.5 alpha level 0.1, multiplier*stddev/sqrt(sample size)= 1.64485*0.02/5.47723 0
If you enter
you will get
*** TEST RESULT 1 *** Summary Z-Test null hypothesis H0 mu1=mu2, alt. hyp. H1 mu1<mu2. Test returns 0 if probability to observe data is less than 0.05 (null hyp. mu1=mu2 rejected with less than alpha probability error) Test returns 1 otherwise (can not reject null hypothesis) Data mean mu1=0.48, population mean mu2=0.5 alpha level 0.05, multiplier*stddev/sqrt(sample size)= 1.64485*0.1/7.07107 1
