Modified producer consumer problem: assume one producer process and n consumer processes share a bounded buffer having b slots. the producer deposits messages in the buffer; consumers fetch them. every message deposited by the producer is to be eventually received by all n consumers. furthermore, each consumer is to receive the messages in the order they were deposited. however, consumers can receive messages at different times. for example, one consumer could receive up to b more messages than another if the second consumer is slow. a) develop a monitor to synchronize the two types of threads (draw the monitor picture, give the thread execution pseudo-code, give service methods’ pseudo-code, initialization, condition variables). extensively comment your implementation. use the concept of monitors: condition variables have names, are implemented as queues with fifo policy. you can use any of the two signal policies but specify which one you use. don't use notifyall. b) is it possible for the pseudo-code of your service methods to support the other (not chosen) signal policy? if no, explain why not.

Researchers measured the data speeds for a particular smartphone carrier at 50 airports. the highest speed measured was 78.1 mbps. the complete list of 50 data speeds has a mean of x overbarequals16.11 mbps and a standard deviation of sequals18.65 mbps. a. what is the difference between carrier's highest data speed and the mean of all 50 data speeds? b. how many standard deviations is that [the difference found in part (a)]? c. convert the carrier's highest data speed to a z score. d. if we consider data speeds that convert to z scores between minus2 and 2 to be neither significantly low nor significantly high, is the carrier's highest data speed significant? a. the difference is nothing mbps.
