Use the test statistic to determine the p-value. 4. The result is statistically significant if the p-value is less than or equal to the level of significance.

We will fail to reject the null (commit a Type II error) if we get a Z statistic greater than -1.64. 3. This -1.64 Z-critical value corresponds to some X critical value (Xcritical), such that 30 ( 1.64) | 0.95 ...

All we do is calculate a t-statistic for this null hypothesis and our data and see if that test statistic is unlikely under the null distribution (the Student’s t-distribution). Unfortunately, when we have more complicated hypotheses, this test no longer works.
Understanding the Dependent t Test

That is, the average reaction time for the alcohol condition (M = 42.07) was significantly longer (slower) than the average reaction time for the no …
