Young children in the united states are exposed to an average of 4.0 hours of backgroundtelevision per day. having the television on in the background while children are doing other activitiesmay have adverse consequences on a child’s well-being. you have a research hypothesis that childrenfrom low-income families are exposed to more than 4.0 hours of daily background television. in orderto test this hypothesis, you have collected a random sample of 60 children from low-income familiesand found that these children were exposed to a sample mean of 4.5 hours of daily backgroundtelevision. based on a previous study, you are willing to assume that the population standard deviationis 1.0 hours. use .01 as the level of significance. a) develop hypotheses that can be used to test your research hypothesis. b) what is the p-value based on your sample of 60 children from low-income families? what is yourhypothesis test decision based on p-value approach? c) repeat the test using the critical value approach. what is your hypothesis test decision? d) state your conclusion for the study.
