Construct the indicated confidence interval for the difference between the two population means. Assume that the assumptions and conditions for inference have been met. A researcher was interested in comparing the number of hours of television watched each day by two-year-olds and three-year-olds. A random sample of 18 two-year-olds and 18 three-year-olds yielded the following data: 2-year-olds 0.5 1.5 3-year-olds 2.0 3.0 1.5 2.0 1.5 1.5 1.5 1.0 0.0 1.5 2.0 1.0 1.0 0.0 2.0 1.5 0.0 1.5 2.5 2.0 1.5 2.0 0.5 0.0 2.5 2.0 1.5 2.5 0.0 3.0 1.0 0.5 1.0 1.5 Determine a 99% confidence interval for the difference, u - Han between the mean of two-year-olds' TV watching and the mean GPA of three-year-olds' TV watching. O A. (-1.14, 0.53) O B. (-1.26, 0.65) OC. (-1.16, 0.55) O D. (-1.06, 0.45) O E. (-0.98, 0.37)
