Test Statistic: which is NOT found on the regression printout. You will, however, find bj and s{bj} on the printout. Sampling Distribution: Under the null hypothesis the statistic follows a t-distribution with n - p degrees of freedom. Reject in the upper or lower tail of this distribution, making the appropriate adjustment for one-sided tests.

The probability that the test statistic will take on a value that is at least as extreme as the observed value of the statistics when the null hypothesis is true. It is the smallest level of significance at which the null hypothesis would be rejected. It is customary to call the test statistic (and the data) significant when the null hypothesis ...

The test statistic measures how much the sample data diverge from the null hypothesis. If the test statistic is large and is in the direction suggested by the alternative hypothesis, we have data that would be unlikely if the null hypothesis were true. We make “unlikely” precise by calculating a probability called a …

A test statistic measures how far away the corresponding sample statistic is from the parameter value(s) specified by H0. If the sample statistic is extremely far from the value(s) in H0, we say the test statistic falls in the “rejection region” and we reject H0 in favor of Ha.

The standardized observed test statistic is: (we will discuss the second case in the next section) The Decision Tool (THE TEST STATISTIC) In order to perform the hypothesis test, we first determine the value of the observed statistic of our sample. Many hypotheses are tested using a statistical test based on the following general formula:

A common test statistic is a t-value. In this case, we are testing the value of one population mean, and the t-value (or sometimes used - a z value) is a measure of “how far” the sample mean is from the population mean that is specified in the null hypothesis.

The p-value associated with the observed value of the test statistic is the probability of getting the observed value or a value more extreme (in the direction of Ha), assuming H0 is true. The p-value represents the probability of observing a sample outcome more contradictory to …
