Answer 1

Solution-

For a one-tail (lower) hypothesis test, if the z- or t-test statistic exceeds the critical value, we do not reject the null hypothesis.

- Answer is False.

If test statistics is greater than critical value then we reject the null hypothesis.

In hypothesis testing, a critical value is a value on the test distribution that is compared to the test statistic to determine whether to reject the null hypothesis. If the absolute value of test statistic is greater than the critical value, you can decide statistical significance and reject the null hypothesis.
