Document Summary

Reject h0 at the 5% significance level since 2. 04>1. 96: using =. 01. Do not reject h0 at the 1% level since 2. 04<2. 575. Note: values that form the dividing line between rejecting and not rejecting. E. g. in (a) 1. 96 is the 5% critical value. P. value method for testing about a population mean for n 30 the above procedure is called the critical value method. Case i: p. value = area under the z curve to the right of z. Case ii: p. value = area under the z curve to the left of z. Case iii: p. value = 2x the area to the right of |z| All cases: reject h0 at significance level if the p. value< . Example: p-value = 2x area to the right of |2. 04| Step 2: same as index card but replace z by tn 1.
