Let X be normally distributed with mean μ = 2,800 and standard deviation σ = 900[You may find it useful to reference the z table.]

a. Find x such that P(X ≤ x) = 0.9382. (Round "z" value to 2 decimal places, and final answer to nearest whole number.)

b. Find x such that P(X > x) = 0.025. (Round "z" value to 2 decimal places, and final answer to nearest whole number.)

c. Find x such that P(2,800 ≤ X ≤ x) = 0.1217. (Round "z" value to 2 decimal places, and final answer to nearest whole number.)
d. Find x such that P(X ≤ x) = 0.4840. (Round "z" value to 2 decimal places, and final answer to nearest whole number.)
