Answer 1

Select the phrase that best completes the following, "The test statistic is

A) A standard deviation and tells you the distance and direction from the null

Explanation:

We know that the test statistic follows a standard score form the underlying distribution with respective parameters. The value of the test statistic indicates that how the data vary from the null value. Also, the sign of the test statistic indicates the direction from the null hypothesis value. Thus, it is the standard deviation which tells you the distance and direction from the null.
