When do you use the Z interval instead of the t interval? The one-sample t test: How does it compare with the Z test from 6.2? When is it correct to use this procedure? When do you use the Z test instead of the t test? Know how and when to use the t interval dialog on your calculator, and how to interpret the results (STAT > TESTS > T Interval).

Recognize from the design of a study whether one-sample t, paired t, or two-sample t procedures are needed. Two-Sample t Procedures. Calculate and interpret a confidence interval for the difference between two means. Use the two-sample t statistic with conservative degrees of freedom if you do not have statistical software.

You might make a statement in a report like this: A one-sample t-test between proportions was performed to determine whether there was a significant difference between the percent choosing candidate A and candidate B. The t-statistic was not significant at the .05 critical alpha level, t(106)=1.808, p=.073.
