Question

Question 1 In communications let p denote the probability that a bit sent by the transmitter will be received erroneously on the other end of the channel. A telecom company has determined that for a communication channel an error rate of p > 0.05 is unacceptable. To perform the test, a predetermined 32 bit long message is sent (this is a sample with n = 32) and the number of erroneous bits are counted at the receiving end. The number of erroneous bits is 2. (a) Using a hypothesis test at level 0.01, can we conclude that the data present sufficient evidence to suggest that the rate p is unacceptable?
