Give bounds for the attained significance level

Reference no: EM131029035

A study was conducted by Joseph Jacobson and Diane Wille to determine the effect of early child care on infant-mother attachment patterns.5 In the study, 93 infants were classified as either "secure" or "anxious" using the Ainsworth strange-situation paradigm. In addition, the infants were classified according to the average number of hours per week that they spent in child care. The data appear in the accompanying table.

Attachment Pattern

Low
(0-3 hours)

Moderate
(4-19 hours)

High
(20-54 hours)

a. Do the data indicate a dependence between attachment patterns and the number of hours spent in child care? Test using α = .05.

b. Give bounds for the attained significance level.
