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 24 months and determines the rate of retum for a certain fund. The standard deviation of the rate of retum is computed to be 2.71%. Is there sufficient evidence to conclude that the fund has moderate risk at the a = 0,05 level of significanco? A normal probability plot indicates that the monthly rates of retum are normally distributed What are the correct hypotheses for this test? The nult hypothesis is How The alternative hypothesis is HET Calculate the value of the test statistic 7. (Round to three decimal places as needed) Use technology to determine the value for the best statistic The P-value is (Round to three decimal places as needed) What is the correct conclusion of the 0.05 level of significance? Since the P value is W than the level of significance moderate risk at the 0.05 level of significance the null hypothesis. There Y sufficient evidence lo conclude that the fund has

Suppose 221 subjects are treated with a drug that is used to treat pain and 50 of the developed nausea. Use a 0.01 significance level to test the claim that more than 20% of users develop nausea.
