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, higher scores indicated stronger fine motor skills. Summary statistics are given below:
Difference | n | Sample Difference | Std. Err. | Min | Max |
d = Pre - Post | 37 | -7.8109 | 2.0715 | -36 | 9 |
If the investigation is done in hopes of supporting that the occupational therapy is improving fine motor skills for kindergarten students, identify each of the following for the appropriate hypothesis test? Round all values to 4 decimal places.
T =
p-value = < (Note that this T-stat is not in the chart and so we will identify the p-value as less than the last value provided in the corresponding row. Due to the limits of the chart, we can use this last value as this answer, realizing that the true p-value is less than this and provides the sufficient evidence to support the effectiveness of the occupational therapy for kindergarteners.)
