For problem #3, refer to the table at the top of this file, and also Tables.pdf
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.
Ho: 4 = 2.3 Hạ: u<2.3
Left-tailed a = .05
P= .0668
+ must be a value from Tables.pdf that came in a separate file with this exam, not technology
Zc = -1.645 + from the table at this top of this file, not technology
Critical Value method: z> ze
Careful: Use the right symbols in HO and H1 in the problems below depending on if the clatm relates to a
proportion or to a mean.
P-Value method: P >a
Fail to reject the null hypothesis
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
