Answer :
The mean hip measurement for women's size 6 jeans is 36.9 inches, which is the average value reported from the study. The standard deviation is used to measure variation but is not needed to determine the mean value. Therefore option a) 36.9 inches
The question provided is related to statistics, a branch of mathematics, and it involves understanding the mean and standard deviation of a data set. Considering the information provided from a large study, the mean hip measurement for women's size 6 jeans is 36.9 inches. This mean value represents the average hip measurement and is derived directly from the study. There is no need to adjust this value by the standard deviation to answer the question presented.
It is important to note that standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range. However, in this case, we are only asked for the mean, so the standard deviation is not used in the calculation.
