The normalt command uses the Z test to test the mean of data.
Examples.
*** 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 |

*** 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 |
