Asked by Koylar
A factory produces a particular type of electronic component. The probability of a component being acceptable is 0.95. The components are packed in boxes of 24.
(i) Calculate the probability that a box, chosen at random, contains exactly 22 acceptable components.
All the boxes are inspected and a box is rejected if it contains fewer than 22 acceptable components.
(ii) Calculate the probability that a box, chosen at random is rejected. The factory produces 80 boxes per day over a long period of time.
(iii) Estimate the mean and standard deviation of the number of boxes rejected per day.
