Over a 2-year period, 34 European women with previous gestational diabetes were retrospectively recruited from West London antenatal databases for a study conducted by Kousta et al. (A-30). One of the measurements for these women was the fasting nonesterified fatty acids concentration (NEFA)

measured in mmol=L. In the sample of 34 women, the mean NEFA level was 435 with a sample standard deviation of 215.0. Construct a 95 percent confidence interval for the mean fasting NEFA level for a population of women with gestational diabetes. State all necessary assumptions about the reported data and subjects.
