Researchers found that a person in a particular country spent an average of 4.5 hours a day watching TV in 2010. Assume the population standard deviation is 1.7 hours per day. A sample of 45 people averaged 5.2 hours of television viewing per day. Does this result support the findings of the study? zx= = 2.77 (Round to two decimal places as needed.) P(x>5.2) = (Round to four decimal places as needed.) Does this result support the findings of the study? The probability is than 0.05, which means the result less greater the findings of the study.
