Extracted text: Suppose a mutual fund qualifies as having moderate risk if the standard deviation of its monthly rate of return is less than 5%. A mutual-fund rating agency randomly selects 21 months and determines the rate of return for a certain fund. The standard deviation of the rate of return is computed to be 3.37%. Is there sufficient evidence to conclude that the fund has moderate risk at the a = 0.01 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: 0.0337. > The alternative hypothesis is H4: 0.0337. Calculate the value of the test statistic. 0.05. x² = (Round to three decimal places as n 0.0337. Use technology to determine the P-value for tie iosi diaidiu. The P-value is (Round to three decimal places as needed.) What is the correct conclusion at the a = 0.01 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 0.01 level of significance.
