1. Young children in the U.S. are exposed to an average of 4hours of television per day, which can adversely impact a child’swell-being. You are working in a research lab that hypothesizesthat children in low income households are exposed to more than 4hours of television. In order to test this hypothesis, youcollected data on a random sample of 75 children from low incomehouseholds. You found a sample mean television exposure time of 4.5hours. Based on a previous study, you are willing to assume apopulation standard deviation of 0.5 hours. a. Using thisinformation, test your hypothesis using the critical valueapproach; assume a significance level of 10%. b. Calculate thep-value associated with your test statistic. Using the p-valueapproach, what is your hypothesis test conclusion?
