B. Given that \( \quad S S T=\sum_{i=1}^{n}(y-\bar{y})^{2} ; \quad S S E=\sum_{i=1}^{n}(\hat{y}-\bar{y})^{2} \), and SSR \( =\sum_{i=1}^{n} \hat{\mu}_{i}^{2} \), show that \( S S T=S S E+S S R \) and derive an expression for the coefficient of determination \( R^{2} \).

onsider the PPF represented above. If points A and B represent 22 apples and 32 oranges respectively; What is the opportunity cost of producing an additional apple? Record your unitless answer as a positive number to the nearest two decimal places.
EXAMPLE 5-4 Heating of a Gas in a Tank by Stirring An insulated rigid tank initially contains 1.5 lbm of helium at 80°F and 50 psia. A paddle wheel with a power rating of 0.02 hp is operated within the tank for 30 min. Determine (a) the final temperature and (b) the final pressure of the helium gas. SOLUTION We take the contents of the tank as the system (Fig. 5-17). This is a closed system since no mass crosses the system boundary during the process. We observe that there is paddle work done on the system.
