You have a portfolio with $15,000 invested in Stock A with a beta of 2.5, $25,000 invested in stock B with a beta of 0.7, and $10,000 invested in Stock C with a beta of 1.0. If the risk-free rate is 2% and the market risk premium is 6%, what is the required return of the portfolio?

Determine the cross correlation function between the two sets of data

x1(n)= {1.5, 2.0, 1.5, 2.0, 2.5}, and x2(n)= {0, 0.33, 0.67, 1.0} using:

1- Direct Cross-Correlation definition

2- Applying the Correlation Theorem and DFT

The material correction factor is 1.0. Assume slot dozing, and a 50 min/hr job efficiency. For weight, wet sand is pretty close to 2300 pounds per Cy. Excluding grade, what is my net correction factor for the other factors (excluding grade)?

A skateboarder starts up a 1.0-m-high, 30? ramp at a speed of 7.2m/s . The skateboard wheels roll without friction. At the top, she leaves the ramp and sails through the air.

How far from the end of the ramp does the skateboarder touch down?

A portfolio manager summarizes the input from the macro and micro forecasters in the following table:

a. Calculate expected excess returns, alpha values, and residual variances for these stocks. (Negative values should be indicated by a minus sign. Do not round intermediate calculations. Round "Alpha values" to 1 decimal place.)

b. Compute the proportion in the optimal risky portfolio. (Do not round intermediate calculations. Enter your answer as decimals rounded to 4 places.)

1. Let X and Y equal the number of milligrams of tar in filtered and nonfiltered cigarettes, respectively. Assume that ?~?(?_?, ?²) and ?~?(?_?, ?²). We shall test the null hypothesis ?₀: ?_? = ?_? against the alternative hypothesis ?_?: ?_? < ?_? using independent random samples of sizes n = 9 and m = 11 observations from X and Y, respectively.
   1. Define the test statistic for testing the above hypothesis, and the rejection region that is associated with an ? = 0.01 significance level. Sketch a figure illustrating this rejection region.
   2. Given the n = 9 observations on X: 0.9, 1.1, 0.1, 0.7, 0.4, 0.9, 0.8, 1.0, 0.4; and the m = 11 observations on Y: 1.5, 0.9, 1.6, 0.5, 1.4, 1.9, 1.0, 1.2, 1.3, 1.6, 2.1, calculate the value of the test statistic and clearly state your conclusion. Locate the value of the test statistic on your figure.
   3. What is the p-value of this test?
