Extracted text: Let x be a random variable representing dividend yield of Australian bank stocks. We may assume that x has a normal distribution with o 2.6%. A random sample of 17 Australian bank stocks has a sample mean of x 8.76%. For the entire Australian stock market, the mean dividend yield is u= 6.5%. Do these data indicate that the dividend yield of all Australian bank stocks is higher than 6.5%? Use a = 0.01. Are the data statistically significant at the given level of significance? Based on your answers, reject or fail to reject the null hypothesis? %3D will you Question 3 options: The P-value is less than than the level of significance and so the data are not statistically significant. Thus, we reject the null hypothesis. The P-value is less than than the level of significance and so the data are statistically significant. Thus, we fail to reject the null hypothesis. The P-value is greater than than the level of significance and so the data are statistically significant. Thus, we reject the null hypothesis. The P-value is greater than than the level of significance and so the data are not statistically significant. Thus, we fail to reject the null hypothesis. The P-value is less than than the level of significance and so the data are statistically significant. Thus, we reject the null hypothesis.
