Final answer:
a. 3.32%. The dividend yield for Sierra Slumber common stock is 3.32%.
Step-by-step explanation:
The dividend yield is calculated by dividing the annual dividend per share by the current stock price, and expressing it as a percentage. In this case, the last annual dividend is $1.26 per share, and the current stock price is $38.007. Therefore, the dividend yield is calculated as:
Dividend Yield = (Annual Dividend / Stock Price) x 100%
Dividend Yield = ($1.26 / $38.007) x 100% = 3.32%
Therefore, the correct answer is 3.32% (option a).
