-/1 POINTS BBBASICSTAT7 11.R.010. MY NOTES ASK YOUR TEACHER The following problem is based on information taken from the pediatrics section of The Merck Manual (a commonly used reference in medical schools and nursing programs). Let x be the body weight of a child (in kilograms), and let y be the metabolic rate of the child (in 100 kcal/24 h). X 17.0 18.0 10.0 18.0 6.0 24.0 12.0 12.0 8.9 8.3 1.7 8.9 1.9 8.4 4.8 2.2 Ex = 117; Zy = 45.1; Ex2 = 1937; Zy2 = 332.25; Exy = 774.9 (a) Find Se. (Round your answer to three decimal places.) (b) Find r. (Round your answer to three decimal places.) Test that p is positive. Use a = 0.01. (Round your answers to three decimal places.) t = critical t = Conclusion: At the 1% level of significance, there is sufficient evidence to conclude that the population correlation coefficient is greater than zero. O At the 1% level of significance, there is insufficient evidence to conclude that the population correlation coefficient is greater than zero. (c) Find b. (Round your answer to three decimal places.) Test that B is positive. Use a = 0.01. (Round your answers to three decimal places.) t = critical t = Conclusion: At the 1% level of significance, there is sufficient evidence to conclude that the slope of the population least-squares line is positive. O At the 1% level of significance, there is insufficient evidence to conclude that the slope of the population least-squares line is positive. (d) Find the equation for the least-squares line y. (Round your answers to three decimal places.) y = X(b) Find r. (Round your answer to three decimal places.) Test that p is positive. Use a = 0.01. (Round your answers to three decimal places.) t = critical t = Conclusion: O At the 1% level of significance, there is sufficient evidence to conclude that the population correlation coefficient is greater than zero. O At the 1% level of significance, there is insufficient evidence to conclude that the population correlation coefficient is greater than zero. (c) Find b. (Round your answer to three decimal places.) Test that B is positive. Use a = 0.01. (Round your answers to three decimal places.) t = critical t = Conclusion: O At the 1% level of significance, there is sufficient evidence to conclude that the slope of the population least-squares line is positive. At the 1% level of significance, there is insufficient evidence to conclude that the slope of the population least-squares line is positive. (d) Find the equation for the least-squares line y. (Round your answers to three decimal places.) y = Find a 90% confidence interval for the predicted metabolic rate for a child weighing 10 kg.
