WebMore information about critical values for the t-distribution : First of all, critical values are points at the tail (s) of a specific distribution, with the property that the area under the curve for those critical points in the tails is equal to the given value of \alpha α. The distribution in this case is the T-Student distribution. WebFor a test with \ (\alpha\) = 0.05 and \ (\beta\) = 0.10, the minimum sample size required for the test is $$ N = (1.645 + 1.282)^2 = 8.567 \approx 9 \, . $$. More often we must compute the sample size with the population standard deviation being unknown. The procedures for computing sample sizes when the standard deviation is not known are ...
