Having the television on in the background while children are doing other activities may have adverse consequences on a child's well-being. You have a research hypothesis that children from low-income families are exposed to more than 4 hours of daily back- ground television. In order to test this hypothesis, you have collected a random sample of 60 children from low-income families and found that these children were exposed to a sample mean of 4.5 hours of daily background television. a Develop hypotheses that can be used to test your research hypothesis. b. Based on a previous study, you are willing to assume that the population standard deviation is o = 1.5 hours. What is the p-value based on your sample of 60 children from low-income families? c. Use a = .01 as the level of significance. What is your conclusion? 67. Starting Salaries for Business Graduates. Michigan State University's Collegiate Employment Research Institute found that starting salary for recipients of bachelor's degrees in business was $50,032 in 2017. The results for a sample of 100 business majors receiving a bachelor's degree in 2018 showed a mean starting salary of $51,276 with a sample standard deviation of $5200. Conduct a hypothesis test to determine whether the mean starting salary for business majors in 2018 is greater than the mean starting salary in 2017. Use a = = .01 as the level of significance. 68.
