Suppose a mutual fund qualifies as having moderate risk if the standard deviation of its monthly rate of return is less than 49%. A mutual-fund rating agency randomly selects 28 months and determines the rate of return for a certain fund. The standard deviation of the rate of return is computed to be 2.75%. Is there sufficient evidence to conclude that the fund has moderate risk at the o=0.05 level of significance? A normal probability plot indicates that the monthly rates of return are normally distributed. What are the correct hypotheses for this test? The null hypothesis is Ho: The alternative hypothesis is H,: Calculate the value of the test statistic. (Round to three decimal places as needed.) Use technology to determine the P-value for the test statistic. The P-value is (Round to three decimal places as needed.) What is the correct conclusion at the @ = 0.05 level of significance? Since the P-value is than the level of significance, the null hypothesis. There sufficient evidence to conclude that the fund has moderate risk at the 0.05 level of significance
