A Canadian longitudinal study, examine whether giving antibiotics in infancy increases the likelihood that the child will be over weight later in life. The children were classified as having received antibiotics or not during the first year of life and then being overweight or not at 9 years old. The study included 616 children, and the results are shown in the table below. overweight not overweight total antibiotics 144 294 438 no antibiotics 37 141 178 total 181 435 616 round your ansers to three decimal places. WHAT PROPORTION OF ALL CHILDREN IN THE STUDY WERE GIVEN ANTIBIOTICS DURING THE FIRST YEAR OF LIFE? WHAT PROPORTION OF ALL CHILDREN IN THE STUDY WERE CLASSIFIED AS OVERWEIGHT AT AGE 9? WHAT PROPORTION OF THOSE RECEIVING ANTIBIOTICS WERE CLASSIFIED AS OVERWEIGHT AT AGE 9? WHAT PROPORTION OF THOSE NOT RECEIVING ANTIBIOTICS WERE CLASSIFIED AS OVERWEIGHT AT AGE 9? IF WE USE PA TO DENOTE THE PROPORTION FROM PART(C) AND PN TO DENOTE THE PROPORTION FROM PART(B) CALCULATE THE DIFFERENCE IN PROPORTION BEING OVERWEIGHT, PA -PN, BETWEEN THASE THAT WERE EXPOSED TO ANTIBIOTICS AND THOSE THAT WERENT.
