Hi. I need to know the test statistic as well as the P-value here.

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 22 months and determines the rate of return for a certain fund. The standard deviation of the rate of return is computed to be 4.33%. Is there sufficient evidence to conclude that the fund has moderate risk at the a = 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: = 0.05. The alternative hypothesis is H1: 6
