Indicate whether the following statement is true or false.

If we do not reject the null hypothesis, it is possible we have made both type I and type II errors.

In an upper tail hypothesis test for the mean, the critical value is 2.575 and the test statistic is 2.5. In this case, the null hypothesis should not be rejected.

The calculated p-value should be divided by 2 to make the decision for a two tail test.

The sampling error is always positive.
