Let X be a random variable representing dividend yield of Australian bank stocks. We may assume that X has a normal distribution with standard deviation Q=2.4% A random sample of 19 Australian bank stocks has a sample mean of x=8.71%. For the entire Australian stock market the mean dividend yield is U= 5.9%. Do these data indicate that the dividend yield of all Australian bank stocks is higher than 5.9%? Use Q = .05. Are the data statistically significant at the given level of significance? Based on your answers, will you reject or fail to reject the null hypothesis?

A. The p-value is less than the level of significance and so the data are not statistically significant. Thus, we reject the null hypothesis. B. The p-value is less than the level of significance and so the data are statistically significant. Thus, we fail to reject the null hypothesis. C. The p-value is greater than the level of significance and so the data are statistically significant. Thus, we fail to reject the null hypothesis. D. The p-value is greater than the level of significance and so the data are not statistically significant. Thus, we reject the null hypothesis. E. The p-value is less than the level of significance and so the data are statistically significant. Thus, we reject the null hypothesis
