Textbook Problem

A researcher selects a sample from a population with a mean of µ. = 60 and administers a treatment to the individuals in the sample. If the researcher predicts that the treatment will increase scores, then

**a.**Using symbols, state the hypotheses for a one-tailed test.**b.**For the one-tailed test, would the critical region be located in the right-hand tail or the left-hand tail of the distribution?

**(a)**

To determine

**To state:** The null hypothesis and alternative hypothesis for one-tailed test.

Explanation

The test hypothesis are given below:

Null hypothesis:

That is, the mean score is less than or equal to 60

**(b)**

To determine

**To identify:** The location of the critical region for one tailed test.
