An all$-$equity firm is considering the following projects:

Project Beta IRR

W $\mathrm{.}839\mathrm{.}4\%$

X $\mathrm{.}9211\mathrm{.}6\%$

Y $1\mathrm{.}0912\mathrm{.}9\%$

Z $1\mathrm{.}3514\mathrm{.}1\%$

The T$-$bill rate is $4$ percent, and the expected return on the market is $12$ percent.

Which projects would be incorrectly accepted or rejected if the firms$$ overall cost of capital of $12\%$ were used as a hurdle rate?
