grow across the stem. These roots prevent proper development of the trunk and compress the tree’s vascular system, eventually causing the tree to weaken and die.

Refer to Exercise 25. Assume that if m = 0, the value s = – 1.5 is sent, and if m = 1, the value s = 1.5 is sent. The value received is X, where X = s + E, and E ~ N(0, 0.64). If X ? 0.5, then the receiver concludes that m =0, and if X > 0.5, then the receiver concludes that m = 1.

a. If the true message is m = 0, what is the probability of an error, that is, what is the probability that the receiver concludes that m = 1? b. If the true message is m = 1, what is the probability of an error, that is, what is the probability that the receiver concludes that m = 0? c. A string consisting of 601s and 400s will be sent. A bit is chosen at random from this string. What is the probability that it will be received correctly? d. Refer to part (c). A bit is chosen at random from the received string. Given that this bit is 1, what is the probability that the bit sent was 0? e. Refer to part (c). A bit is chosen at random from the received string. Given that this bit is 0, what is the probability that the bit sent was 1?
