Question: (d) Compute Cook's distance measure for these data. (Round your answers to two decimal places.) Cook's X; yi Distance 22 17 24 26 26 36



(d) Compute Cook's distance measure for these data. (Round your answers to two decimal places.) Cook's X; yi Distance 22 17 24 26 26 36 28 40 40 75 Are any observations influential? Explain. (Select all that apply.) O Observation x; = 22 is an influential observation since it has a large Cook's distance measure (greater than 1). Observation x; = 24 is an influential observation since it has a large Cook's distance measure (greater than 1). O Observation x; = 26 is an influential observation since it has a large Cook's distance measure (greater than 1). Observation x; = 28 is an influential observation since it has a large Cook's distance measure (greater than 1). O Observation x; = 40 is an influential observation since it has a large Cook's distance measure (greater than 1). O None of the observations are influential since they do not have large Cook's distance measures (greater than 1).A statistical program is recommended. You may need to use the appropriate appendix table or technology to answer this question. Data For two \\.-'arial:llesf X and y, follow. (a) Develop the estimated regression equation for these data. (Round your numerical values to two decimal places.) 9 = 48.28 + 3.11:: I (c) Compute the leverage values for these data. (Round your answers to two decimal places.) X ; Leverage yi Value 22 17 24 26 26 36 28 40 40 75 Do there appear to be any influential observations in these data? Explain. Because the leverage value for ---Select--- is greater than we conclude that there ---Select--- V
