Let X be normally distributed with mean μ = 126 and standard deviation σ = 22. [You may find it useful to reference the z table.]


a. Find P(X ≤ 100). (Round "z" value to 2 decimal places and final answer to 4 decimal places.)



b. Find P(95 ≤ X ≤ 110). (Round "z" value to 2 decimal places and final answer to 4 decimal places.)



c. Find x such that P(X ≤ x) = 0.410. (Round "z" value and final answer to 3 decimal places.)



d. Find x such that P(X > x) = 0.820. (Round "z" value and final answer to 3 decimal places.)
