Summing-up

___Test Statistics: [000]or[010]

___H0: Normal Data ______ <GUV-N>
__________[000]__[001]__[010]__[011]______Crit. Values__
_n=100___0.762__0.025__0.190__0.023_____1.64, 3.90, 3.52
_________[000]+[010]= 0.952
___150___0.753__0.031__0.195__0.022_____1.64, 3.88, 3.56
___________________= 0.948
___200___0.752__0.032__0.195__0.021_____1.64, 3.87, 3.59
___________________= 0.947

___Ha: Uniform Data______ <GUV-U>
__________[000]__[001]__[010]__[011]_____
_n=100___0.014__0.968__0.000__0.017_____
__________[000]+[010]= 0.014
___150___0.000__0.984__0.000__0.016_____
___________________ = 0.000
___200___0.000__0.984__0.000__0.016_____
___________________ = 0.000

Alpha, Power


___n=100_______1- 0.952= 4.8%________98.6%
_____150______________= 5.2%______ 100.0%
_____200-_____________ = 5.3%______ 100.0%


Conclusion: for the range of sizes 100-200 the test efficacy is excellent: it´s able to make distinction between Normal Distribution (H0) and Uniform (Ha).
