In a random sample of 32 large cap mutual funds, the average YTD return is 3.05% with a standard deviation of 9.77%. Conduct by hand an appropriate hypothesis test at the 5% level to test whether the average YTD return for a large cap mutual fund is positive. (Again, that means to write the hypotheses, compute the test statistic, and estimate the p-value.) Give your test conclusion in terms of the question being asked. Confirm your test statistic and result...

A financial planner wants to compare the yield of income- and growth-oriented mutual funds. Fifty thousand dollars is invested in each of a sample of 35 income-oriented and 40 growth-oriented funds. The mean increase for a two-year period for the income funds is $1100. For the growth‑oriented funds the mean increase is $1090. At the 0.01 significance level is there a difference in the mean yield of the two funds? Assume that σ1 = $45 and σ2 = $55....

Please help! Only Multiple Choice.
3. The average return from equity mutual funds over a period was 2 %. It is desired to test if the returns from growth fund over the same period exceed that of the equity fund. A sample of 9 growth funds showed an average retun of 2.183 % . It is known from past data that the standard deviation of the age of returns for growth funds is 0.2%. If we test H0 : μ-2...

sample mean = 213.4552 sample Standard deviation = 44.81542 N=50 alpha = .05 SEM = 6.337857477 For each of the following hypothesis testing problems, manually calculate the t-statistic, use the 5% level of significance (alpha = 0.05), determine the rejection region, determine the p-value of the t-test, use the 95% confidence interval in part (c) to make a decision about whether or not to reject the null hypothesis. Test the null hypothesis that the true mean is 225 versus the...

A financial planner wants to compare the yield of income and growth mutual funds. Fifty thousand dollars is invested in each of a sample of 35 and 40 growth funds. The mean increase for a two-year period for the income funds is 900$. For the growth funds, the mean increase is 875$. Income funds have a sample standard deviation of 35$; growth funds have a sample standard deviation of 45$. Assume that the population standard deviations are equal. At the...

In the last quarter of 2007, a group of 64 mutual funds had a mean return of 5.5% with a standard deviation of 7.7%. If a normal model can be used to model them, what percent of the funds would you expect to be in each region? Use the 68-95-99.7 rule to approximate the probabilities rather than using technology to find the values more precisely. Be sure to draw a picture first. a) Returns of negative 17.6% or less ...

Suppose the returns of a particular group of mutual funds are normally distributed with a mean of 10.9% and a standard deviation of 4.6%. If the manager of a particular fund wants his fund to be in the top 10% of funds with the highest return, what return must his fund have? (please round your answer to 2 decimal places)
