Suppose a mutual fund qualifies as having moderate risk if the standard deviation of its monthly rate of return is less than 3%. A mutual-fund rating agency randomly selects 22 months and determines the rate of return for a certain fund. The standard deviation of the rate of return is computed to be 2.08%. Is there sufficient evidence to conclude that the fund has moderate risk at the α = 0.10 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 H₁: Calculate the value of the test statistic. x² = (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 x = 0.10 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 0.10 level of significance.

### Assessing the Risk Level of a Mutual Fund Suppose a mutual fund qualifies as having moderate risk if the standard deviation of its monthly rate of return is less than 3%. A mutual fund rating agency randomly selects 22 months and determines the rate of return for a certain fund. The standard deviation of the rate of return is computed to be 2.08%. Is there sufficient evidence to conclude that the fund has moderate risk at the α = 0.10 level of significance? A normal probability plot indicates that the monthly rates of return are normally distributed. --- #### Hypothesis Testing **What are the correct hypotheses for this test?** - The null hypothesis is \( H_0: \sigma \) [dropdown] - The alternative hypothesis is \( H_1: \sigma \) [dropdown] **Calculate the value of the test statistic.** - \(\chi^2 =\) [Textbox] (Round to three decimal places as needed.) **Use technology to determine the P-value for the test statistic.** - The P-value is [Textbox]. (Round to three decimal places as needed.) **What is the correct conclusion at the \(\alpha = 0.10\) level of significance?** - Since the P-value is [dropdown] than the level of significance, [dropdown] the null hypothesis. There [dropdown] sufficient evidence to conclude that the fund has moderate risk at the 0.10 level of significance. --- By completing the above steps, you can determine whether the mutual fund's risk level qualifies as moderate based on the given data and significance level.
