A developmental psychologist interested in the attachment between full-term and pre-term infants and their mothers conducted a study to measure infant willingness to explore a strange environment by counting the number of toys infants handled during a five minute interval. Four groups of infants, two comprised of full-term infants and two of per-term infants, were observed both when their mothers were present and when their mothers were absent. The data is presented in the table that follows: Baby Birth Condition Mother Full-term Full-term # of Toys (toys). 7 Identify one of the independent variables: Present Present Full-term Present 5 Full-term Present 5 Full-term Absent 6. Full-term Absent 4 Identify the other independent variable: 7 Full-term Absent 5 Full-term Pre-term Absent Present 4 6. Present Present 4 10 Pre-term Pre-term Pre-term 11 5 12 Present Absent Identify the dependent variable: 13 Pre-term 3 Absent 14 15 16 Pre-term Pre-term Pre-term 4 Absent Absent 2 4 Using SPSS test all main and interaction effects at the .05 level of significance. Create a table including the cell means and marginal means and label each variable and level. State your null decision and conclusion (Step 5 of hypothesis testing) for all main and interaction effects. Label each effect clearly. Report in APA format the F statistics for all main and interaction effects. Be sure to report the "best" p value possible.
