Suppose a mutual fund qualifies as having moderate risk if the standard deviation of its monthly rate of return is less than 6%. A mutual-fund rating agency randomly selects 23 months and determines the rate of return for a certain fund. The standard deviation of the rate of return is computed to be 4.35%. Is there sufficient evidence to conclude that the fund has moderate risk at the a3D0.10 level of significance? A normal probability plot indicates that the monthly rates of returm are normally distributed. What are the correct hypotheses for this test? The null hypothesis is H,: 0.06. The alternative hypothesis is H,: 0.06.

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.
