7. When determining whether to include or exclude a variable in regression analysis, if the p-value associated with the variable’s t-value is above some accepted significance value, such as 0.05, then: the variable is a candidate for inclusion. the variable is a candidate for exclusion. the variable is redundant

The one-sample t statistic is. The P-value is found from the t(19) distribution (n-1=20-1=19). Table D shows that 3.86 lies between the upper 0.001 and 0.0005 critical values of the t(19) distribution. The P-value lies between 0.0005 and 0.001. Software gives the value P=0.0053. “The improvement in score was significant (t=3.86, df=19, p=0 ...

Now in the output below, we can see the results for the T-test. Look at the enlarged numbers under the column that says “t” for the t-value, “df” for the degrees of freedom, and “Sig. (2-tailed) for the p-value. (Notice that the p-value of .539 is greater than our “.05” alpha level, so we fail to …
