Problem 10: (10% of Assignment Value) An irregularly shaped object is suspended in a tank of water. The mass of the object is m and the apparent mass (when submerged) is $\frac{9}{10}m$. The pressure above the tank is $P_0$. Both of the bottom faces of the object are horizontal and rectangular. The top of the tank is open to the atmosphere. Given the dimensions in the figure and the density (Q) of the water, determine the force on the top of the object from the fluid. $F_{top}$ =

3. Internal Validity, which is the strength of the inference that A causes B, is: A. Threatened by small sample size, since chance differences between the treatment and control groups can then be more disruptive of accurate interpretation of the dependent variable(s). B. Threatened by the blinding of participants to study design, as this interferes with the psychometric properties of the independent variable measures. C. Primarily addressed through study design, whereas external validity is primarily achieved through gathering a large, representative, and adequately diverse sample. D. Of the utmost concern in correlational research.

Q3 5.1-15. If X is N($\mu$, $\sigma^2$), then M(t) = E($e^{tX}$) = exp($\mu$t + $\sigma^2t^2$/2), $-\infty$ < t < $\infty$. We then say that Y = $e^X$ has a lognormal distribution because X = ln Y. (a) Show that the pdf of Y is 1 g(y) = \frac{1}{y\sqrt{2\pi\sigma^2}} exp[-($ln$y - $\mu$)^2/2$\sigma^2$], 0 < y < $\infty$.
