Suppose Intel stock has a beta of $0\mathrm{.}75,$ whereas Boeing stock has a beta of $1\mathrm{.}28.$ If the risk$-$free interest rate is $3\mathrm{.}5\%$ and the expected return of the market portfolio is $13\mathrm{.}8\%,$ according to the CAPM,

a$.$ What is the expected return of Intel stock?

b$.$ What is the expected return of Boeing stock?

c$.$ What is the beta of a portfolio that consists of $65\%$ Intel stock and $35\%$ Boeing stock?

d$.$ What is the expected return of a portfolio that consists of $65\%$ Intel stock and $35\%$ Boeing stock? $($There are two ways to solve this.$)$
