One positive side-effect of bipolar encoding is that a bipolar violation (two consecutive + pulses or two consecutive —pulses separated by any number of zeros) indicates to the receiver that an error has occurred in , upon the receipt of such a violation, the receiver does not know which bit is in error (only that an error hasoccurred). The received bipolar sequence has one bipolar violation. Construct two scenarios (each of which involves adifferent transmitted bit stream with one transmitted bit being converted via an error) that will produce this same receivedbit pattern.«I» - O + - O - +

Which is cheaper: eating out or dining in? the mean cost of a flank steak, broccoli, and rice bought at the grocery store is $13.04 (money. msn website, november 7, 2012). a sample of 100 neighborhood restaurants showed a mean price of $12.75 and a standard deviation of $2 for a comparable restaurant meal. a. develop appropriate hypotheses for a test to determine whether the sample data support the conclusion that the mean cost of a restaurant meal is less than fixing a comparable meal at home. b. using the sample from the 100 restaurants, what is the p-value? c. at a = .05, what is your conclusion? d. repeat the preceding hypothesis test using the critical value approach
