Twenty university students (chosen at random from students enrolled at the University of Verm took part in an experiment testing the effect of watching FOX News vs. CNN on knowledge of w events. The 20 participants were divided into two equal groups of 10 participants each. One gre was assigned to watch FOX and the other was assigned to watch CNN. Participants then watch their assigned station (FOX or CNN) for three hours a night for four weeks. At the end of the for week perlod they were administered a test of world knowledge. The results were as follows: m 110, mCNN 99, Srox 10, SCNN6. Compute the lower limit of the 95% confidence interval around mFox - MCNN. (Please give you answer to two decimal places.) 3.09

Question 16: Twenty university students (chosen at random from students enrolled at the University of Vermont) took part in an experiment testing the effect of watching FOX News vs. CNN on knowledge of world events. The 20 participants were divided into two equal groups of 10 participants each. One group was assigned to watch FOX and the other was assigned to watch CNN. Participants then watched their assigned station (FOX or CNN) for three hours a night for four weeks. At the end of the four- week period they were administered a test of world knowledge. The results were as follows: mrox = 110, meNN = 99, srox = 10, SCNN = 6. Compute the lower limit of the 95% confidence interval around mFox - MCNN. (Please give your answer to two decimal places.) 3.09 For the data provided in Quesiont 16, compute the lower limit of the approximate 95% confidence interval around the estimate of ő computed from mrox- mcNN (Please round your answer to two decimal places.) Question 17: For the data provided in Quesiont 16, compute fobe based on mrox- MCNN- (Please round your answer to two decimal places.) Question 18:
