Let X be normally distributed with mean = 25 and standard deviation = 20. [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 > 3). (Round "z" value to 2 decimal places and final answer to 4 decimal places.)
c. Find P(6 X 23). (Round "z" value to 2 decimal places and final answer to 4 decimal places.)
d. Find P(8 X 30). (Round "z" value to 2 decimal places and final answer to 4 decimal places.)
