Question
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 o = 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 H,: The alternative hypothesis is H Click to select your answer(s) and then click Check Answer. parts remaining Clear All Check Answer
