Part B Before making a final decision on the production plan to adopt, the bakery's manager decides to contact Professor Leung in the Math Department to conduct a market research survey. The results of the survey will indicate either favourable or unfavourable market conditions for premium breads. In the past, when there was low demand, Professor Leung's predictions were unfavourable 70%% of the time. The professor's predictions have also been favourable given medium demand 52% of the time, and unfavourable given high demand 20% of the time. Assume prior probabilities of 0.1 and 0.4 for high and medium demand respectively. a. Calculate posterior (revised) probabilities and enter them in the table below. Round answers to 3 decimal places, do not round intermediate results. Note ! The first cell of the table sepresents P (Low Favourable) The last cell of the table represents P(High Unfavourable) Low Medium High Favourable Unfavourable b. Determine the marginal probabilities of favourable and unfavourable predictions P( Favourable) P( Unfavourable) Question Help. = Message instructor Submit
