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.
