Suppose a mutua fund cualfes as having moderate fisk ti the standand deviation of its monthly rate of return is less than 6\%. A mutual-fund rating apency randomly selects 22 months and determines the rate of retum for a certain fund. The standard deriation of the rate of retum is computed to be 5 saya is there saficient evidence to conclude that the fund has moderate riak at the \( \alpha=0.10 \) level of signilicance? A normal probabily plot indicates that the monthly rates of retum are nomally distributed. What are the correct hypotheses for this test? \begin{tabular}{l} The null hypothesis is \( \mathrm{H}_{0}=2 \) \\ The aternative trpothesis is \( \mathrm{H}_{1} \mathrm{\mu} \quad 0.06 . \) \\ \hline \end{tabular} Calculate the value of the test statistic. \( x_{0}^{2}=\square \) (Round is two deciral places as needed) Use technology to determine the P-value for the lest statistic. The Pualue is (Pound to three decimal places as needed) What is the comect conclusion af the \( \alpha=0.10 \) level of significanoe? Since the P.value is \( \quad \nabla \) than the level of significance, do net mitet the null hypothesis. There is not unficient evidence to condude the the fund has moderate risk at the \( 0.10 \) level of significance.
