Suppose a mutual fund qualifies as having moderate risk if the standard deviation of its monthly rate of return is less than 4%. 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 3.42%. Is th. sufficient evidence to conclude that the fund has moderate risk at the α=0.05 level of significance? A normal probabiiliy plot indicates that the monthly rates of return are normally distributed. What are the correct hypotheses for this test? The null hypothesis is H_0 The alternative hypothesis H_1 Calculate the value of the test statistic. x²₀ = ..... (Round to two 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 α=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.
