A study was conducted to determine the effect of early child care on infant-mother attachment patterns. 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. Attachment Hours in Child Care Moderate (4-19 hours) High (20-54 hours) Pattern Low (0-3 hours) Secure 24 35 Anxious 11 10 8. Do the data indicate a dependence between attachment patterns and the number of hours spent in child care? Test using a =0.05. Find bounds for the attained significance level.
