Suppose a mutual fund qualifies as having moderate risk if thestandard deviation of its monthly rate of return is less than 66?%.A? mutual-fund rating agency randomly selects 27 months anddetermines the rate of return for a certain fund. The standarddeviation of the rate of return is computed to be 4.48?%. Is theresufficient evidence to conclude that the fund has moderate risk atthe ?=0.10 level of? significance? A normal probability plotindicates that the monthly rates of return are normallydistributed. What are the correct hypotheses for this? test?Calculate the value of the test statistic. Use technology todetermine the? P-value for the test statistic. What is the correctconclusion at the ?=0.10 level of? significance?
