You have 64 companies in your portfolio. The average return of portfolio is 0.14 and the standard deviation is 0.16. The standard error of the mean is closest to:

There are ____ number of steps in hypothesis testing?

What is the mean-reverting level to which changes in the unemployment rate converge? The unemployment rate is estimated using the following model:∆URt= b0 + b1∆URt-1+ €tUsing monthly observations from March 2015 to December 2019 you estimate the following.  Regression Statistics R Squared 0.2184 Standard Error 0.1202 Observations 58 Durbin-Watson 2.1852   Coefficients Standard Error t Stat Intercept -0.0405 0.0161 -2.51 ∆URt-1 -0.4674 0.1181 -3.96

For a standard normal distribution F(0) equals:

You believe that there should be a positive relationship between returns and systematic risk. The appropriate alternate hypothesis is:

Consider thefollowing information on two securities Expected rate  of return on Security Ri   = 0.10                      Expected rate of return on Security Rj    = 0.20 Variance of ROR of security Ri      =  0.16       Variance of ROR of security Rj      = 0.25Covariance between Ri and Rj = -0.04The variance of Global Minimum Variance portfolio is:

In the following table Ri is the return on stock i and Rm is the return on market. The estimate of the tcritical for αi at 5% level of significance is closest to: t Ri Rm (Rm-Rmbar)^2 error^2 Rm^2 1 0.080 0.100 5.625E-05 0.0000 0.01 2 -0.040 0.130 0.000506 0.0005 0.0169 3 0.040 0.120 0.000156 0.0007 0.0144 4 0.130 0.080 0.000756 0.0001 0.0064 Total 0.21000 0.43000 0.001475 0.0013 0.0477 Mean 0.05250 0.10750 variance 0.00516 0.00049 covariance -0.00153   SEE 0.02535

Use the following information:   Number of Forecast Mean Forecast Error SD of Forecast Errors Analyst A          101             0.05 0.10 Analyst B          121            0.02 0.09      For Analyst A, 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?

Your portfolio of assets has a mean return of 12% and a standard deviation of 22%. You can buy a one-year T-bill that yields 5.5%. This yield is effectively a one-year risk-free interest rate. What is the probability that your portfolio’s return will be equal to or less than the risk-free rate?
