Height velocity graphs are used by endocrinologists to follow the progress of children with growth deficiencies. The given figure shows the height velocity curves of an average boy and an average girl between ages 3 and 18.

(a) Which curve is for girls and which is for boys? Explain how you can tell.

(b) About how much does the average boy grow between ages 3 and 10 ?

(c) The growth spurt associated with adolescence and the onset of puberty occurs between ages 12 and 15 for the average boy and between ages 10 and 12.5 for the average girl. Estimate the height gained by each average child during this growth spurt.

(d) When fully grown, about how much taller is the average man than the average woman? (The average boy and girl are about the same height at age 3.)

Suppose an analyst reformulates financial statements to prepare the alternative decomposition of ROCE for a firm with no debt. The analyst determines that the company holds excess cash as large marketable equity securities. The result will be net financial obligations that are negative. Assume that operating ROA is positive and large. How will this affect the decomposition of ROCE = Operating ROA + (Leverage x Spread)? How do you interpret the net borrowing rate for this firm?

(a) Using the given figures, find the average value on $0 \leq x \leq 2$ of

(i) f(x)

(ii) g(x)

(iii) $f(x) \cdot g(x)$

(b) Is the following statement true? Explain your answer.

Average(f) $\cdot$ Average(g) = Average(f $\cdot$ g)

During 2011, Crawford Furniture Company purchases a carload of wicker chairs. The manufacturer sells the chairs to Crawford for a lump sum of $60,000, because it is discontinuing manufacturing operations and wishes to dispose of its entire stock.

$$\begin{array}{|c|c|c|} \hline \text { Type } & \text { No. of Chairs } & \text { Estimated Selling Price Each } \\ \hline \text { Lounge chairs } & 400 & \$ 90 \\ \hline \text { Armchairs } & 300 & 80 \\ \hline \text { Straight chairs } & 800 & 50 \\ \hline \end{array}$$

During 2011, Crawford sells 200 lounge chairs, 100 armchairs, and 120 straight chairs.
