Question 71

a simple binary communication channel carries messages by using only two signals; say 0 and 1. We assume that; for a given binary channel, 40% of the time a 1 is transmitted; the probability that a transmitted 0 is correctly received is 0.90,and the probability that a transmitted 1 is correctly received is 0.95. given 1 is received, probability that 1 was transmitted

The following probability distributions of job satisfaction scores for a sample of information systems (IS) senior executives and middle managers range from a low of 1 (very dissatisfied) to a high of 5 (very satisfied).

My newspaper is delivered late 60 percent of the time. Suppose deliveries can be described as a Bernoulli process and define a random variable X to be the number of late deliveries per year (365 days). Find the mean and standard deviation of X
