Let x be a random variable representing dividend yield of the Australian bank stocks. We may suppose that x has normal distribution with ? = 2.6%. A random sample of 24 Australian bank stocks has sample mean of x= 9.76%. For the whole Australian stock market, the mean dividend yield is µ= 9.3%. Do such data indicate that the dividend yield of all Australian bank stocks is higher than 9.3%? Employ ? = 0.1. If the sample test statistic z = 0.867, find (or estimate) the P-value.
