Abstract
This paper presents the interval estimate for specific points in polynomial regression: zero of a linear regression, abscissa of the extreme of a quadratic regression, abscissa of the inflection point of a cubic regression. Two different approaches are under study. An application of these two approaches based on quadratic regression in presented: interval estimate for the plant density giving optimal yield of maize is under consideration.
