Assume that a sample is used to estimate a population proportion p. Find the 90% confidence interval for a sample of size 228 with 14.9% successes. Enter your answer as an open-interval (i. e., parentheses) using decimals (not percents) accurate to three decimal places.
90% C. I. =
Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "
