3. State the null and alternative hypotheses, state whether left/right/two-tailed, find the P-Value, find the critical value, should we reject Ho, or should we fail to reject Ho at the 5% level of significance? Show making the decision using both the P-value method and the critical value method. Example: The test statistic of z = -1.5 is obtained when testing the claim that u<2.3. Họ: 4 = 2.3 H:: 4<2.3 Left-tailed a = .05 + must be a value from Tables.pdf that came in a separate file with this exam, not technology P=.0668 Ze = -1.645 + from the table at this top of this file, not technology P-Value method: P >a Fail to reject the null hypothesis Critical Value method: z > ze Careful: Use the right symbols in HO and H1 in the problems below depending on If the clalm relates to a proportion or to a mean. As noted above, P and ze should not come from technology (answer may differ in the last decimal place) a The test statistic of z =-1.98 is obtained when testing the claim that u = 0.475 b. The test statistic of z = 1.23 is obtained when testing the claim that p> 0.3 c. The test statistic of z = -2.57 is obtained when testing the claim that u < 0.75
