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 27 months and determines the rate of return for a certain fund. the standard deviation of the rate of return is computed to be 2.19%. is there sufficient evidence to conclude that the fund has moderate risk at the alpha equals 0.05 level of significance? a normal probability plot indicates that the monthly rates of return are normally distributed.
