Let X be normally distributed with mean μ = 10 and standard deviation σ = 6. [You may find it useful to reference the z table.]


a. Find P(X ≤ 0). (Round "z" value to 2 decimal places and final answer to 4 decimal places.)

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

c. Find P(4 ≤ X ≤ 10). (Round "z" value to 2 decimal places and final answer to 4 decimal places.)

d. Find P(6 ≤ X ≤ 14). (Round "z" value to 2 decimal places and final answer to 4 decimal places.)
