Explanation / Answer

Answer to the following question is here:

P(X<15) = .311

a. Now, to determine the area under the density curve that lies to the left of 15 = P(X<15) = .311

b. Now, to determine the area under the desisity curve that lies to the right of 15

= P(X>15) =

= 1- P(X<15) [or 1- area to the left]

= 1-.311

= 0.689
