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.

The data in the table represent the height of an object over time. which model best represents the data? height of an object time (seconds) height (feet) 05 1 50 2 70 3 48 quadratic, because the height of the object increases or decreases with a multiplicative rate of change quadratic, because the height increases and then decreases exponential, because the height of the object increases or decreases with a multiplicative rate of change exponential, because the height increases and then decreases
