Calculate a 95% confidence interval for a portfolio return with a normal distribution for returns. The mean return is 10% and the standard deviation is 10%?

In a city, annual household incomes are normally distributed with a mean of$175,000 and a standard deviation of $25000. What is the percentage of households with income greater than $150,000?

VarA=225 and Varb=100. The coefficient of correlation between A and B is -1.The fraction of A in the minimum variance portfolio is:

VarA=225 and VarB=100 Above what threshold coefficient of correlation diversification benefits are not possible is:

The appropriate null hypothesis to test whether the mean of a population is greater than 25 is: The population mean is:

Which of the following statements is correct for a hypothesis test with a probability of Type I error of 5% and Type II error of 15%?

You design a test of whether abnormal returns are positive on average. The test results in a p-value of 4%. You can:

For Example 7.2 the confidence interval for the alpha of 0.01 and 49 degrees of freedom is?

For the regression question in class, the confidence interval for alpha at 5% level of significance and 4 degrees of freedom is?

For Analyst B, determine, using t-test find whether the null hypothesis of zero mean test of forecasting quality is rejected at the 0.01 level of significance?

Obtain the 95% confidence interval for Analysts A, mean forecasting error.

Formulate and test the null and alternative hypothesis consistent with determining whether the population mean value of Analyst As forecast errors ( ) are larger 1 than Analyst Bs. Use t-test.
