Consider the following sample information for variable X, where A = Asians, E= Europeans, t=time : Derive
- Consider the following sample information for variable \(\mathrm{X}\), where \(\text{A}\) = Asians, \(\mathrm{E}=\) Europeans, \(\mathrm{t}=\mathrm{time}\) :
- Derive and draw X's probability distribution.
- Compute X's mean, variance, standard deviation, median and mode.
- Draw X's Box-and-Whiskers Plot.
- Group X into 4 intervals and derive and draw the histogram.
- Draw X's time graph.
- For X, compute the grouped mean, grouped variance and grouped standard deviation.
- Derive and draw A's and B's probability distributions in terms of X.
- Using the corresponding values for X, compute A's and B's means, variances, standard deviations, medians and modes.
- Using the corresponding values for X, draw A's and B's Box-and-Whiskers Plots in the same diagram.
(2) Let \(\mathrm{Y}=2+5 \mathrm{X}^{2}, \mathrm{~W}=3+6 \mathrm{Z}^{2}\) (where \(\mathrm{Y}, \mathrm{X}, \mathrm{W}\) and \(\mathrm{Z}\) are all random variables) and data for \(\mathrm{X}\) and \(\mathrm{Z}\) be as follows: \([\mathrm{X}: 4,5,7,1]\) and \([\mathrm{Z}: 8,3,6,9]\)
Compute the following: \(E(Y), E(W), \operatorname{COV}(Y W), \operatorname{CORR}(\mathrm{YW}), \operatorname{VAR}(2 \mathrm{Y}+0.5 \mathrm{~W})\).
(3) A portfolio of risky investments consists of stocks \(\mathrm{Y}\) and \(\mathrm{X}\) with the following sample holding period returns (where t=time):
- Draw a time diagram displaying \(\mathrm{Y}\) and \(\mathrm{X}\) in the same graph.
- Compute the correlation coefficient between \(\mathrm{Y}\) and \(\mathrm{X}\) and draw the scatter plot with a representative line through it.
- Draw the Efficient Frontier of the portfolio and identify the spending percentages that minimize risk.
