Question

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:

Difference	n	Sample Diff	Std. Err.	Min	Max
d = Pre - Post	37	-7.8109	2.0715	-36	9

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.

Ho - μd = 0
Ha - μd < 0

α = _____

Reject Ho if probability is ______ (<,>,=) α

TS: t = _____

probability =

Therefore we _________ (Reject Ho/Do Not reject Ho)

At the 0.05 level, there __________(is/is not) significant evidence to conclude occupational therapy strengthens the mean fine motor scores.
