jushmkSample size, N = 255 students Number of those owning a car = 111 Z at 99% confidence = 2.58 Now, Point estimate, p = 111/255 = 0.43529 True proportion = p+/- Z*Sqrt [p(1-p)/N] = 0.43529 +/- 2.58*Sqrt[0.43529(1-0.43529)/255] = 0.43529+/-0.0801 = (0.355186,0.51539) Re-writing into ten-thousandths decimal places: True proportion = (0.3552,0.5154)
