In each hypothesis test round all calculated P-values to 4 decimal Dlaces, round all critical z, t, and *values to 3 decimal places, round the test statistic z, t, and *values to 3 decimal places. DO NOT ROLND the endpoints of any confidence intervals. STUDENTS MUST: 2. 4. 6. 7. 8. 9. Write in a mathematically correct manner the claim and the opposite of the claim. Write the null hypothesis Ho con-ectly using the symbol Ho: with the colon : Write the altemate hypothesis HI conectly using the symbol HI : with the colon. Wllichever is the claim, Ho or HI, IVYRITE the word "claim" after the hypothesis. Write the level of significance a. Write down whether the test is a left-tailed test, a right-tailed test, or a two- tailed test. Indicate the probability distribution (z, t, or *distribution) that fits the problem. Detemline the appropriate critical value(s) for the problem. Indicate the test command used: I-PropZTest, 2-PropZTest, Z-Test, 2- SampZTest, T-Test and 2-SampTTest. HRITE down the value of the test statistic z, t or rounded to 3 decimal places and ALWAYS give the P- value rounded to 4 decimal places. Unless I state othemvise, give TWO reasons for your decision of rejecting or failing to reject the null hypothesis. The FIRST reason based on whether the test statistic z, t, or falls in the critical rejection. The SECOND reason based on whether the P-value is a. Based on whichever was the claim Ho or HI, STATE whether there is sufficient sample evidence to support the claim or insufficient sample evidence to support the clann at the level of signifi cance u.
