Small Sample Mean Problem. A study was done to determine the effect of vitamin supplements for the mother on the birth weight of babies. The sample size was 17. All the women in the study regularly visited a doctor during their pregnancy. The data below show the summary statistics and a stem and leaf plot of the birth weight of the 17 babies. Weight is in kilograms (kg).
