Let X be normally distributed with mean μ = 2.4 and standard deviation σ = 1.6.

a. Find P(X > 6.5). (Round "z" value to 2 decimal places and final answer to 4 decimal places.

b. Find P(5.5 ≤ X ≤ 7.5). (Round "z" value to 2 decimal places and final answer to 4 decimal places.)
c. Find x such that P(X > x) = 0.0869. (Round "z" value and final answer to 3 decimal places.)
d. Find x such that P(x ≤ X ≤ 2.4) = 0.3944. (Negative value should be indicated by a minus sign. Round "z" value and final answer to 3 decimal places.)
