Suppose Intel stock has a beta of $1\mathrm{.}16,$ whereas Boeing stock has a beta of $2\mathrm{.}32.$ If the risk$-$free interest rate is $4\mathrm{.}88\%$ and the expected return of the market portfolio is $12\mathrm{.}28\%,$ 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 $70\%$ Intel stock and $30\%$ Boeing stock?

d$.$ What is the expected return of a portfolio that consists of $70\%$ Intel stock and $30\%$ Boeing stock? $($There are two ways to solve this.$)$

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

The expected return of Intel stock is $\%.($Round to two decimal places.$)$
