Fluid inclusions are microscopic volumes of fluid that are trapped in rock during rock formation. The article "Fluid Inclusion Study of Metamorphic Gold-Quartz Veins in Northwestern Nevada, U.S.A.: Characteristics of Tectonically Induced Fluid" (S. Cheong, Geosciences Journal, 2002:103-115) describes the geochemical properties of fluid inclusions in several different veins in northwest Nevada. The following table presents data on the maximum salinity (% NaCi by weight) of inclusions in several rock samples from several areas.

find the minimum for the upper quartile
One way to identify penguin colonies is to examine thermal (surface temperature) maps of an area. Penguins appear warmer than their background (remember penguins are mammals). Suppose that on Torgersen Island, thermal values for a colony of penguins are uniformly distributed with a maximum thermal value of 18^{\circ}C18∘C.It has been reported that 20% of colonies report a thermal value of at least 15^{\circ}C15∘C. Based on this information, determine the minimum thermal value for colonies on Torgersen Island.

ANSWER LETTER D ONLY Two measurements method are used to evaluate the surface smoothness of a paper product. Let X and Y denote the measurement of each of the two methods. a). Suppose that the joint p.d.f. of X and Y is modeled by fxy(x,y) =c, 0<x<4,0<y and x-1<y<x | 1. Determine the value of c. b). Determine the marginal probability distribution of X. Find also the mean and variance of X. c). Determine the conditional probability distribution of Y given X-2. Find also the conditional mean and conditional variance of Y given X=2. d.) Check if the measurements of the two methods X and Y are independent
