Smoking Mothers: A Research

Introduction:
The purpose of this study is to see if there is a link between the birth weight and gestation of newborn babies with smoking mothers and non- smoking mothers. The significance of this investigation is to find a relationship between the two as it might help with health benefits. The features in the investigation are the relationship between the two sets of data between the birth weight and the gestation period of smoking mothers and non-smoking mothers.
Part A:
The median for the whole data set is 3067.5 pounds for birth weight and 39 weeks for gestation period.
The mean birth weight for infants born to smoking mothers is 92.5 pounds less than the infants born to non-smoking mothers. This is a small number compared to the birth weight so it …show more content…
For a child from a mother who smokes, we would expect the birth weight, to be less than that of a child from a non-smoking mother. For a mother who smokes, we would expect the gestation period to be longer than that of non-smoking mothers. For the equation of least squares regression and the line of best fit for the for the birth weight and gestation period of a smoking mother there was a strong positive linear relationship and for the birth weight and gestation period of a non-smoking mother there was a strong positive linear relationship. Bias could have been created in this dataset by surveying more smoking mothers than non-smoking mothers or by surveying more non-smoking mothers than smoking. A bigger sample size could lead to more outliers. The sample size was 32 data points which are accurate for an investigation. However if there was to be a bigger sample size the more accurate the findings would be. The relationship between the two sets of variables for the birth weight and gestation period of smoking mothers and non-smoking mothers are very
