Please show the full solution and proper notation and terminology. 1. A production manager wants to estimate the proportion of defective parts received from a new supplier. She believes that defective proportion is no more than 0.20 and wants to be within 0.02 of the true proportion of defective parts with 90% level of confidence. How large a sample should she take? thanks.
