One tailed distribution: Steps for finding the area in a z-table Step 1: Look up your z-score in the z-table. Looking up the value means finding the intersection of your two decimals (see note above). For example, if you are asked to find the area in a one tailed distribution ...

Use Student's t distribution table to find the critical value t alpha/ 2t alpha/ 2 corresponding to a 90% confidence interval and 28 degrees of freedom. We would like to test the hypotheses H0: mu = 80 and HA: mu not equal to 80. We find t = 1....
