Suppose a test procedure about the population mean μ is performed,when the population is normal with an unknown variance,and a sample of size 20 is drawn from the population.If the alternative hypothesis is H₁ : μ μ₀,then the null hypothesis is rejected at a level α = 0.05 if t 1.729.

Question

Suppose a test procedure about the population mean μ is performed,when the population is normal with an unknown variance,and a sample of size 20 is drawn from the population.If the alternative hypothesis is H₁ : μ > μ₀,then the null hypothesis is rejected at a level α = 0.05 if t > 1.729.

This is true because if the calculated t-value is greater than the critical value of 1.729, then we reject the null hypothesis and accept the alternative hypothesis. This is true for a one-tailed test with a significance level of 0.05.
