For a one-tailed t test, there is only one critical cutoff value.
True
False
True.
For one tailed t test there is only one critical cutoff value.
As t distribution is symmetric. So if the test is right tailed then for level of significance the critical value is . if observed t value is greater than this the the null hypothesis will be rejected.
Similarly for left tailed test the critical value is . If observed t is less than this then null hypothesis will be rejected.
