A marketing director would like to estimate the effect of advertising expenditures (AE) on the quantity of his product sold (Q) controlling for the effects of price (P) and average household income (I) in the area. The estimated regression coefficient multiplying AE is equal to 7.762 with a p-value of 0.0021. He tests this hypothesis that the coefficient multiplying AE is equal to 7.5; the the p-value of the test statistic is equal to 0.50. The test size is 5%. He should: A) Fail to reject Ho and conclude that the coefficient is not significantly different from 7.5. B) Reject Ho and conclude that the coefficient is not equal to 7.5. C) Fail to reject Ho and conclude that the coefficient is equal to 7.5 D) Reject Ho and conclude that the coefficient is equal to 7.5 E) Reject Ho and conclude that the coefficient is not significantly different from 7.5.

For the following questions consider the system in the figure. The mass $m$ is on a frictionless table, circling the hole while it is being pulled in slowly by the attached string. At $t_0$ it is at radius $r_0$ and moving with speed $v_0$. 9) What is/are the conserved quantity/quantities while the string is being pulled? a) $\vec{L}$ and $\vec{p}$ b) $\vec{p}$ only c) $ME$ only d) $\vec{L}$ only e) $\vec{L}$, $\vec{p}$ and $ME$ 10) What is the speed $v(r)$ of the mass $m$ when it is at radius $r$? a) $v_0r_0^2/r$ b) $v_0r/r_0$ c) $v_0r_0/r$ d) $v_1r_1/r^2$ e) $v_0$ 11) What is the tension $T(r)$ on the string when the mass $m$ is at radius $r$? a) $mv^2$ b) $mv^2/r$ c) $mv^2/r_0$ d) $mv^2/r^2$ e) $mv^2r$ 12) What is the total work done by the person pulling the string while the radius is reduced from $r_0$ to $r_0/2$? a) $\frac{3}{2}mv_0^2r_0$ b) $\frac{1}{2}mv_0^2$ c) $mv_0^2$ d) $\frac{1}{2}mv_0^2$ e) $mv_0^2/r_0$

Suppose the position of an object moving horizontally after t seconds is given by the function s(t) = 80t - 15, where 0?t?2 and s is measured in feet, with s > 0 corresponding to positions to the right of the origin. When is the object farthest to the right? The object is farthest to the right at t = \boxed{} s. (Simplify your answer.)
