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 28 months and determines the rate of return for a certain fund, the standard deviation of the rate of return is computed to be 2.82%. is there sufficient evidence to conclude that the fund has moderate risk at the alpha = 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 h0:
the alternative hypothesis is h1:
calculate the value of the test statistic. x 2 0 =
use technology to determine the p-value for the test statistic. the p-value is (round to three decimal places as needed.) what is the correct conclusion at the alpha = 0.10 level of significance? since the p-value is than the level of significance, the null hypothesis. there sufficient evidence to conclude that the fund has moderate risk at the 0.10 level of significance.
