a.	10% or more will be defective? (Round the z-value to 2 decimal places and the final answer to 4 decimal places.)

Probability

b.	less than 1% will be defective? (Round the z-value to 2 decimal places and the final answer to 4 decimal places.)

Probability

c.	more than 10% or less than 1% will be defective? (Round the z-value to 2 decimal places and the final answer to 4 decimal places.)
