Other files provided with this exam: 1. Equations.pdf 2. Tables.pdf Questions in the final may refer to these other files. Instead of using the z-table in reverse to get a z-value from an area, here is a quick- reference table for the most commonly used values: if a = Area in One Tail a (1-tailed) 0.005 0.01 0.025 0.05 0.10 if a = Area in Two Tails a(2-tailed) 0.01 0.02 0.05 0.10 0.20 c = Confidence Level C 99% 98% 95% 90% 80% Zc = Critical Z-Value (negative if left-tailed, +- if two-tailed), Za/2 for confidence interval Zc/ Za/2 2.576 2.326 1.960 1.645 1.282 When complete, scan to a single PDF file and submit on D2L. Be sure to read the instructions carefully before answering a question. Every small detail asked for in the question must be provided. If a problem asks you to solve a problem in a certain way, it must be solved in that way. If stuck on a question, look through the equation sheet for ideas (although most of the problems can be solved with technology, this might help you think about what type of problem it is). Also look through old worksheets for similar problems. You can simply reject or fail to reject Ho. However, for a final conclusion to a hypothesis test, it must be of the form: At the _ level of significance, there (is) /(is not) sufficient evidence to (reject)/(support) the claim that . (and then write out the entire claim in words, not symbols, do not just say "the claim").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. FOLLOW THE EXAMPLE BELOW! Example: The test statistic of z = -1.5 is obtained when testing the claim that / Zc P-Value method: P > a Fail to reject the null hypothesis Careful: Use the right symbols in HO and H1 in the problems below depending on if the claim 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
