Let x be a random variable representing dividend yield of German bank stocks. We assume that x has a normal distribution with average = 4.7% with SD = 2.4%. My random sample of 64 dividend yields of German bank stocks from the South of Germany had an average of 5.4%. Test if my sample of German bank stocks from the South are statistically different from the rest of Germany. For this test use the critical value of Zc = +-1.96 and and alpha = 0.05. Determine the null and alternative hypothesis. Group of answer choices H0 : population average = 4.7% H1 : population average > 4.7% H0 : population average = 4.7% H1 : population average 4.7% H0 : population average = 5.4% H1 : population average < 5.4% H0 : population average = 5.4% H1 : population average 5.4% For this test use the critical value of Zc = +-1.96 and and alpha = 0.05. Determine the test statistic. Group of answer choices z = -2.33 z = +2.33 z = -0.29 z = +0.29 For this test use the critical value of Zc = +-1.96 and and alpha = 0.05. Determine the null and alternative hypothesis. What is the result of the test? Group of answer choices We can reject the null hypothesis at the α=0.05 level. We cannot reject the null hypothesis at the α=0.05 level. We can reject the alternative hypothesis at the α=0.05 level. We cannot reject the alternative hypothesis at the α=0.05 level.
