Suppose a mutual fund qualifies as having moderate risk if the standard deviation of its monthly rate of return is less than 33%. A mutual-fund rating agency randomly selects 2121 months and determines the rate of return for a certain fund. The standard deviation of the rate of return is computed to be 2.632.63%. Is there sufficient evidence to conclude that the fund has moderate risk at the alpha equals 0.05α=0.05 level of significance? A normal probability plot indicates that the monthly rates of return are normally distributed.
