in a marketing survey, 13 out of the 80 participating adults reported that they would like to purchase a new cell phone in the next month. estimate the number of adults in a community of 7200 adults who would like to purchase a new cell phone in the next month. assume that the sample is representative of the population.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2
