For weight adjustment using hip circumference as the independent variable:

Find a 95% confidence interval when the hip circumference is 100 cm (mu subscript Y vertical bar x or end subscript, when xo=100)

Lower bound= Response Round to 2 decimals

Upper bound= Response Round to 2 decimals

Compare it with the prediction interval for that same hip contour (Y subscript 0, when xo=100):

Lower bound= Response Round to 2 decimals

Upper bound= Response Round to 2 decimals
