In an earlier tutorial, you were introduced to a data set of newborn infants containing information regarding their birth weight, their family's income and their mother's education. In this question, you are given the following information for 5 infants born to a non-smoking mother from the same data set: Observation bwght 2,778 3,600 faminc motheduc 1 37.5 16 2 15.5 7 3,374 1,219 2,835 3 42.5 12 22.5 9 5 22.5 12 You will operate on the above data of 5 observations throughout Q1. The variables are defined as follows: bwght = the infant's birth weight in grams faminc = the family's weekly income in $US thousand dollars motheduc = the mother's education in years (a)(1pt) Reconstruct the following frequency table on your answer sheet and fill in the missing information. Motheduc= 12 Faminc 30 (b)(1pt) Reconstruct the following table on your answer sheet. Compute an estimate of the following conditional means. nswer E(bwght | motheduc =16) E(bwght | motheduc >12) E(bwght | motheduc 15.5) E(bwght |motheduc >10 and faminc>=22.5)
