Kindergarten students were participants in a study investigating fine motor skills of 37 children. The children had their fine motor skills measured before the study (a combination of hand use, eye-hand coordination, and manual dexterity) and again after undergoing 7 months of occupational therapy. With the instrument used, high scores indicated stronger fine motor skills. Summary statistics are given below: n Sample Diff Std. Err. Min Max -7.8109 2.0715 -36| Difference d = Pre - Post37 Determine what positive and negative differences mean regarding a student's fine motor skills. Pay attention to the order of subtraction in the output. o A positive difference means the Select an answer 8 score was greater than the Select an answer e, implying fine motor skills were Select answer e over the 7 months. A negative difference means the Select an answer e score was greater than the Select an answer e score, implying fine motor skills were Select an answer 8 over the 7 months. Can one conclude the fine motor skills in a population similar to these students would be stronger after 7 months of occupational therapy? Use a significance level of 0.05.
