For each of the following examples of tests of hypothesis about µ, show the rejection and nonrejection regions on the t-distribution curve. (a) A two-tailed test with α = 0.01 and n = 15 (b) A left-tailed test with α = 0.005 and n = 25 (c) A right-tailed test with α = 0.025 and n = 22

If the alternate hypothesis states that µ does not equal 4,000, where is the rejection region for the hypothesis test? A. Both tails B. Lower or left tail C. Upper or right tail D. Center

For all hypothesis tests, use both the critical value/rejection region and p-value (separate and label each method) and show each of the 5 steps explicitly. A. The internal revenue service believes that the number of business executives who default on their tasks is larger than the proportion of 'blue collar' workers. Out of 150 business executives, 24 default on their taxes. For a sample of 75 'blue collar' workers has only 8 that default on their taxes. Test the hypothesis...

Let's Consider the Following Hypothesis Ho: µ ≤ 25 Ha: µ > 25 1. Is this Hypothesis: Lower tail, Upper tail, or two tail? 2. What is the Critical Value with α = 0.01? 3. A sample of 40 provided a sample mean of 26.4. The population standard deviation is 6. Then the test Statistic is what 4. What is the P-value =? 5. Do we reject ho, do not reject ho, or neither

Consider the following hypothesis test: H_0: µ <= 25 H_a: µ > 25 A sample of size 40 provided a sample mean of 26.4. The population standard deviation is 6. a) Compute the value of the test statistic, rounding all calculations to 2 decimal places. b) What is the associated p-value? c) Using α = 0.05, what is your conclusion? Enter either "reject" or "fail to reject" without the quotes for what to do with the null hypothesis.

(d) What is your decision regarding H0? (e) Your conclusion. Exercise 6: A stockholder at Critical Securities reported that the mean rate of return on a sample of 10 oil stocks was 12.6 percent with a standard deviation of 3.9 percent. The mean rate of return on...

Use tables in the Appendix to specify the appropriate Rejection Region ONLY for each hypothesis test described below a) H0: σ12 / σ22 = 1 (With sample sizes n1 = 25 and n2 = 16.) Ha: σ12 / σ22 < 1 α = .05 b) H0: There is no significant difference in Block Means. Ha: There is a significant difference in at least some pair(s) of Block Means. α = .01 (With 6 Treatments and 25 Blocks.)
