According to the Doyle Log Rule, the volume V (in board-feet) of a log of length L (in feet) and diameter D (in inches) at the small end is V = ((D - 4)/4)^2 L. Find the rate (in board-feet/in) at which the volume is changing with respect to D for a 24-foot-long log whose smallest diameter is the following. (a) smallest diameter is 8 inches board-feet/in (b) smallest diameter is 16 inches board-feet/in (c) smallest diameter is 24 inches board-feet/in (d) smallest diameter is 36 inches board-feet/in

Analyze and sketch the graph of the function. Identify any intercepts, relative extrema, points of inflection, and asymptotes. f(x) = x * sqrt(49 - x^2) x-intercept (smallest x-value) (x, y) = ( [ ] ) x-intercept (x, y) = ( [ ] ) x-intercept (largest x-value) (x, y) = ( [ ] ) y-intercept (x, y) = ( [ ] ) relative maximum (x, y) = ( [ ] ) relative minimum (x, y) = ( [ ] ) point of inflection (x, y) = ( [ 0,0 ] )

9. The annual earnings of 19 people with a high school diploma and 16 people with an associate's degree are shown below. Can you conclude that there is a difference in the mean annual earnings based on level of education? Use ?= 0.01. Assume the populations are normally distributed and the population variances are not equal. High school diploma | Associate's degree --- | --- X = $32,493 | X =$ 40,907 s = $3118 | s= $6162 n = 19 | 16

8. Use Table 5 to find critical value ( s ) for the following. Assume that the samples are random and independent, the populations are normally distributed, and that population variances are equal. H : ? ? ?, ? = 0.10, n = 11, n = 14 (mean sub one does not equal mean sub two. H : ? > ?, ? = 0.01, n = 12, n = 15 (mean sub one is greater than mean sub two.)
