Suppose a binary message is transmitted through a noisy channel. the transmitted signal s has uniform probability to be either 1 or -1, the noise n follows normal distribution n (0, 4) and the received signal is r s+ n. assume the receiver conclude the signal to be 1 when r 2 0 and-1 when r< 0. 1. what is error probability when one signal is transmitted? 2. what is error probability when one signal is transmitted if we triple the amplitude of the transmitted signal? it means s 3 or -3 with equal probability. 3. what is the error probability if we send the same signal three times (with amplitude 1), and take majority for conlusion? for example, if three received signal was concluded 1,-1,1 by receiver, we determine the transmitted signal to be 1

1.3.25 question suppose 40​% of all voters voted for a particular candidate. to simulate exit polls regarding whether or not voters voted for this​ candidate, five random samples of size 1010 and five random samples of size 10001000 have been generated using technology using a population proportion of 0.400.40​, with the accompanying results. complete parts a through c below. click the icon to view the simulation results. a. observe how the sample proportions of successes vary around 0.400.40. simulation compared to sample prop simulation compared to sample prop 1 ▾ 6 ▾ greater than 0.40 less than 0.40 equal to 0.40 2 ▾ less than 0.40 greater than 0.40 equal to 0.40 7 ▾ greater than 0.40 less than 0.40 equal to 0.40 3 ▾ greater than 0.40 less than 0.40 equal to 0.40 8 ▾ equal to 0.40 greater than 0.40 less than 0.40 4 ▾ greater than 0.40 equal to 0.40 less than 0.40 9 ▾ less than 0.40 greater than 0.40 equal to 0.40 5 ▾ equal to 0.40 less than 0.40 greater than 0.40 10 ▾ equal to 0.40 greater than 0.40 less than 0.40 click to select your answer(s) and then click check answer. 2 parts remaining clear all check answer
