A study of two groups of children since early childhood:
One group of 62 attended preschool.
A control group of 61 children from the same area and similar backgrounds did not attend preschool.
Over 10 year period as adults, 38 of the preschool sample and 49 of the control sample needed social services.
A. Does the study provide significant evidence that children who attend preschool have less need for social services as adults?
B. How large is the difference between the proportions of the preschool and no-preschool populations that require social services?
C. Do inference to answer both questions.
Be sure to explain exactly what inference you choose to do.
Please help me with the set up for all three parts to get started. Thanks
