Increasing the sample size of an opinion poll will (a) reduce the bias of the poll result. (b) reduce the variability of the poll result. (c) reduce the effect of nonresponse on the poll. (d) reduce the variability of opinions. (e) all of the above.

(b) reduce the variability of the poll result.

Step-by-step explanation:

when the sample size of an opinion poll is increased, more data will be gathered about the population, and when there is enough data present, The estimates that is made afterward base on the gathered data will be more accurate compare with when there is small sample size. It should be noted that when the sample size of an opinion poll is increased, it will reduce the variability of the poll result.

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 "
