Extracted text: In a study to estimate the proportion of residents in a city that support the construction of a new bypass road in the vicinity, a random sample of 900 residents were polled. Let X+/900/2 X denote the number in the sample who supported the proposal. To estimate the true proportion in support of the plan, we can compute îi The estimator p has 900 bias OA. 1/900. ОВ. 30/2. OC. 1/(2 x 30). OD. 0, so unbiased. OE. 1/30.
