- If, in a sample of n=20 selected from a normal population, X=59and S=12, what are the critical values of t if the level of significance, α, is 0.05, the null hypothesis, H0, is μ=50, and the alternative hypothesis, H1, is μ≠50? The critical values of t areenter the number of the expression indicating the null hypothesis and enter the number of the expression indicating the alternative hypothesis calculate a z and enter to the second decimal place enter the critical value for z (if using the .01 alpha leave) what do you make about the null? is this an effect or chance?2. The critical value of t is 1.383, the value of the test statistic t = -1.383; therefore, we do not reject H0 a. True b. False
