Answer:
Answer are given below;
Step-by-step explanation:
Let A be the investment in Stock X and remaining (1-A) should be investment in stock Y
Rp=AXRx+(1-A)XRy
13.45%=A*12.06%+(1-A)*8.22%
13.45%=12.06%A+8.22%-8.22%A
13.45%=3.84%A+8.22%
13.45%-8.22%=3.84%A
5.23%/3.84%=A
A=1.36
Now 1-A=1-1.36=.36
Now amount invested in Y shall be =$150,000*.36=$54,000
Beta of portfolio=1.46*(1-.36)+.82*.36=.93+.30=1.23
