The human resources department of a large investment bank announced that the number of people it interviews monthly has a mean of 115 with a standaredeviation of 15.4. The management of the bank suspects that the standard deviation exceeds 15.4. Suppose that the management wants to take a smallsample of months and carry out a hypothesis test to see if its suspicions have support. State the null hypothesis H, and the alternative hypothesis H, that iswould use for this test.Ho: OH₁: 0μ5OSOローロXXa>*3рS20

A large nationwide poll recently showed an unemployment rate of 9% in the US. The mayor of a local town wonders this national result holds true for her town, so she plans on taking a sample of her residents to see if the unemployment rate is significantly different than 9% in her town. Let T represent the unemployment rate in her town. Here are the hypotheses she'll use: Null Hypothesis: T = 0.09 %3D Alternative Hypothesis: T 0.09 Which type of Error has been committed in the following situation? • She concludes the town's unemployment rate is not significantly different to 9% when it is actually 9%.

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…
A sample mean, sample standard deviation, and sample size are given. Use the one-mean t-test to perform the required hypothesis test about the mean, μ, of the population from which the sample was drawn. Use the critical-value approach. Sample mean = 7.1 s = 2.3 n = 18 α = 0.01 H0: µ = 10 H1: µ < 10 The decision is to the null hypothesis. (Enter R if you reject and enter F if you fail to reject)
