Suppose a mutual fund qualifies as having moderate risk if the standard deviation of its monthly rate of return is les- 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 5.37%. Is there sufficient evidence to conclude that the fund has moderate risk at the a=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 Hō: 0 = 0.06. The alternative hypothesis is H₁: 6 < 0.06. Calculate the value of the test statistic. x = (Round to two decimal places as needed.)

3. 3c. A. B. Women have head circumferences that are normally distributed with a mean of 23.55 inches and a standard deviation of 0.93 inches. If the HATS BY CHARLIE company produced hats so that they fit head circumferences between 22.2 inches and 24.2 inches, then what is the probability that a woman can fit into these hats? A. If the HATS BY CHARLIE company produced hats so that they fit head circumferences between 22.2 inches and 24.2 inches, then what is the probability that a randomly selected group of 40 woman can fit into these hats? B. Write a sentence or two that explains your answer to 3B and why you think that answer is correct in connection to your answer in 3A.
