One group of 50 will be raised in captivity and the other 50 are tagged and released into the wid. After 5 yoars, all 100 birds pre collected and weighed. There are more than 10" different ways to regroup the 100 birds into groups of 50 again, so looking at all the combinations would be too time consuming to reproduce. In this case, we can run simulations to determine how the original…
A comp nanufacturer is interested in comparing assembly times for two keyboard assembly processes. Assembly times can vary considerably from worker to worker, and the company decides to eliminate this effect by selecting 12 workers at random and timing each worker on each assembly process. Half of the workers are chosen at random to use Process 1 first, and the rest use Process 2 first. For each worker and each process, the assembly time (in minutes) is recorded, as shown in the table below. 77°F Partly sunny Worker Process 1 Process 2 Difference (Process 1 - Process 2) Send data to calculator V 1 90 Explanation 78 Check 12 2 41 22 19 3 40 32 8 4 65 38 5 65 52 27 13 (a) State the null hypothesis H and the alternative hypothesis H₁.

Based on advancements in drug therapy, a pharmaceutical company is developing Resithan, a new treatment for depression. A medical researcher for the company is studying the effectiveness of Resithan as compared to their existing drug, Exemor. A random sample of 458 depressed individuals is selected and treated with Resithan, and 206 find relief from their depression. A random sample of 429 depressed individuals is independently selected from the first sample and treated with Exemor, and 179 find relief from their depression. Based on the medical researcher's study can we conclude, at the 0.05 level of significance, that the proportion P, of all depressed individuals taking Resithan who find relief from depression is greater than the proportion P₂ of all depressed individuals taking Exemor who find relief from depression? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in…

Ho:μ = 1,500 H:> 1,500 x = 1,515, n = 112, o = 100, a = .10 a. Use the data given to test the following hypotheses. (Round your answer to 2 decimal places.) The value of the test statistic is b. Use the p-value to obtain the results. (Round your answer to 4 decimal places.) Since the p-value of and we is Since the observed = 1,515 is than a .10, the decision is to: c. Solve for the critical value required to reject the mean. (Round your answer to 2 decimal places.) than the critical = Appendix A Statistical Tables ,the decision is to:
