      = invNorm(0.035) = 1.812 ( Need a sample of 329 CSCC students. 25. Traditional Method: When the test statistic (z or t) falls in the tail of the rejection region bordered by the critical values. P-Value Method: When the p-value is less than or equal to the level of significance α. 26. All other conditions being equal, does a larger sample size.

      Students then find the critical values using the invNorm command as they did in Problem 1. Remind students that this is a two-tailed test, so 2.5% of the area under the curve is in each tail. Have students discuss their decision about the hypothesis.

Area is almost the same as the confidence level –but you have to add one tail to get (in essence) the right limit, or critical T-value. For example, find the critical value of T for a 95% confidence when the ...
