Please share answers for Ques 2,

1. Consider the table below:

	Security
	A	B	C	D
	2	3	1	4
	1.5	1.3	0.8	0.9
ei	3	1	2	4

If r_m = 8 and _m = 5, calculate the following:

1. 1. The mean return for each security.
2. 2. The variance of each security's return.
3. 3. The covariance of returns between each security.

2. Using the data from Problem 1 and assuming an equally-weighted portfolio, calculate the following:
   1. _pp
   2. _p²
   3. r_p

Please share the formula for portfolio variance of more than two assets.

Thank you
