text_A: For infants with nonsmoking mothers and low infant birth weight, the probability of high infant mortality is 85%. For infants with nonsmoking mothers and normal infant birth weight, the probability of high infant mortality is 50%. For infants with smoking mothers and low infant birth weight, the probability of high infant mortality is 81%. For infants with smoking mothers and normal infant birth weight, the probability of high infant mortality is 56%. For infants with nonsmoking mothers and with poor health, the probability of normal infant birth weight is 39%. For infants with nonsmoking mothers and with good health, the probability of normal infant birth weight is 65%. For infants with smoking mothers and with poor health, the probability of normal infant birth weight is 1%. For infants with smoking mothers and with good health, the probability of normal infant birth weight is 31%. The overall probability of good health is 95%.
text_B: If we disregard the mediation effect through infant's birth weight, would maternal smoking status positively affect infant mortality?
yes.
