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.
