Question
A publication released the results of a study of the evolution of a certain mineral in the Earth's crust. Researchers estimate that the trace amount of this mineral x in reservoirs follows a uniform distribution ranging between 2 and 10 parts per million. a. Find E(x) and interpret its value. b. Compute P(5<x<9). c. Compute P(x<4). a. Select the correct answer below and fill in the answer box to complete your choice. (Simplify your answer.) A. E(x)=. This value gives the minimum parts per million of the mineral for the collection of all reservoirs on the Earth. B. E(X)= This value gives the mean parts per million of the mineral in each reservoir on the Earth. C. E(X)= |. This value gives the mean parts per million of the mineral for the collection of all reservoirs on the Earth. D. E(x)=. This value gives the maximum parts per million of the mineral for the collection of all reservoirs on the Earth.
