PLEASE TYPE THANK YOU! 1.) A quality control engineer is in charge of testing whether or not 90% of the DVD players produced by his company conform to specifications.

(ii) What is the probability that the engineer unnecessarily requires the entire day's production to be tested if in fact 95% of the DVD players conform to specifications?
