a) Ignore the birth weight (x). If the length of gestation are independently and identically distributed (i.i.d.) with mean u and variance o?, what is the estimate for u and o?, respectively? b) If you now use the birth weight (x) and assume that the length of gestation are (i.i.d.) with variance o² and mean u = Bo + B1X. (i) Compute the estimate for o?. comparison to your estimate in part (a), what does this tell you about this model? (ii) By c) Construct a 95% confidence interval for the slope parameter.
