QUESTION #1

In a study to determine the effect of early child care on Infantmother attachment patterns, 96 Infants were classified as either "secure" or "anxious" using an appropriate measurement scale. In addition, the Infants were classified according to the average number of hours per week that they spent In child care. The data are presented In the table. Low Moderate High (03 hours) (419 hours) (2054 hours) Secure 22 37 7 Anxious 10 11 9 (a) Do the data provide sufficient evidence to indicate that there Is a difference In attachment pattern for the Infants depending on the amount of tIme spent In child care? Test using a = 0.05. State the null and alternative hypotheses. 0 H0: Attachment pattern and amount of time spent In child care are linearly related. : Attachment pattern and amount of time spent In child care are Independent. L) (J : Attachment pattern and amount of time spent in child care are Independent. : Attachment pattern and amount of time spent In child care are dependent. : The number of secure and anxious children are equal. : The number of secure and anxious children are not equal. : Attachment pattern and amount of time spent In child care are dependent. : Attachment pattern and amount of time spent in child care are independent. : Attachment pattern and amount of time spent in child care are independent. : Attachment pattern and amount of time spent in child care are linearly related. Find the test statistic. (Round your answer to two decimal places.) Find the rejection region. (Round your answer to two decimal places.) X2>l State the conclusion. L) H0 is rejected. There Is sufficient evidence to indicate dependence between attachment pattern and time spent in child care. (1 H0 Is not rejected. There Is sufcient evidence to Indicate dependence between attachment pattern and time spent in child care. 0 H0 Is rejected. There Is Insufficient evidence to indicate dependence between attachment pattern and time spent In chlld care. 0 H0 Is not rejected. There Is Insufficient evidence to Indicate dependence between attachment pattern and tIme spent In child care. \f
