(10 points) 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 denote the number in the sample who supported the proposal. To estimate the true proportion in The estimator p has bias support of the plan, we can compute p X+VD00/2 900 O A. 1/(2 x 30). о в. 1/30. ос. 1/900. O D. 30/2. O E. 0, so unbiased.
