2. A developmental psychologist is examining problem-solving ability for grade school children. Random samples of 5-year-old, 6-year-old, and 7-year-old children are obtained with n =three in each sample. Each child is given a standardized problem-solving task, and the psychologist records the number of errors. The data are as follows:___________________________________________________5-year-olds________6-year-olds______7-year-olds____5 6 04 4 1 G=306 2 2 ?X2 = 138________________________________________________T = 15 T = 12 T = 3SS = 2 SS = 8 SS = 2________________________________________________a. Use these data to test whether there are any significant differences among the three age groups. Use ? = .05.SSbetween= ?
