A certain network claims that the average person watched 4.4 hours of television per day last year. A consumer agency believes this value has changed. A random sample of 23 people revealed a mean of 3.123 hours with a standard deviation of 1.126 hours. At the 5% significance level, is there sufficient evidence to conclude that the amount of television watched per day by the average person differed from the network’s claim? Assume the population distribution is approximately normal.   Step 4 of 5 :   Determine the rejection region. Round your answer to three decimal places.
