A stock (S) has an expected return of 15% and standard deviation of 5%. A bond (B) has an expected return of 10% and standard deviation of 2%. Correlation coefficient between S and B is 0.2. An investor wants to allocate 25% of her portfolio to S and the remainder of her portfolio to B. What is the expected return and variance of this portfolio?

Consider the discrete-time filter defined by h = fir1(40,0.2). The coefficients h represent a 40th order filter, with a corner frequency of 0.2 times the Nyquist frequency. Use Matlab help on fir1 to learn more about this command. Plot the frequency response of the filter h using the command freqz. Include this plot in your report.

The nicotine content in a single cigarette of a particular brand is a random variable having a probability distribution with a mean of 4.9 milligrams (mgs) and a standard deviation of 0.2 mg. n = 100 of these cigarettes are chosen at random and the nicotine content of each cigarette is measured.
What is the probability that the mean nicotine content of this sample is between 4.87 mgs to 4.96 mgs?

A diesel engine intakes atmospheric air at 60°F and adds 800 Btu/lbm of energy. If the maximum pressure is 1200 psia, calculate:
(a) the cutoff ratio, rc ;
(b) the thermal efficiency, ? ;
(c) the power output, in hp, for an airflow of 0.2 lbm/sec.
[Hints: Follow the Diesel cycle diagram! For ?, you will need the compression ratio.]
