Kindergarten students were participants in a study investigatingfine motor skills of 37 children. The children had their fine motorskills measured before the study (a combination of hand use,eye-hand coordination, and manual dexterity) and again afterundergoing 7 months of occupational therapy. With the instrumentused, high scores indicated stronger fine motor skills. Summarystatistics are given below:
Can one conclude the fine motor skills in a population similarto these students would be stronger after 7 months of occupationaltherapy? Use a significance level of 0.01. Refer to your answerabove to help with the alternative hypothesis of strengthenedscores.
