A Telecommunications company recently installed a new speech recognition system for its repair calls. In their old system, operators had to press keys on the numeric keypad to answer questions, which led many callers to opt to talk to an operator instead. Under the old system, 94% of the customers had to talk to an operator to get their needs met. They want to do a hypothesis test to determine if the new system has been successful in reducing the...

P1 To test the hypothesis Ho: p = 1/2 against H :p < 1/2, we take a random sample of Bernoulli trials, X,X,..., X.,, and use for our test statistic Y = ¿x, which has a binomial distribution b(n, p). Let the critical region be defined by C ={y:y sc}. Find the values of n and c so that (approximately) a = 0.05 and B = 0.10 when p = 1/4. 1=1
