State park officials were interested in the proportions of campers. They decided to take a sample random sample of n=30 from the first N=300 camping parties that visit the campground. Let y1=0 if the head of the ith party sample does not think the campsite spacing is adequate and y=1 if he does (i=1,2,.....30) Use the data in the table to estimate p. the proportion of campers who consider spacing adequate place a bound on error of estimation. Camper Sampled Response yi 1 2 3 . . . 29 30 1 0 1       1 1 Σyi=25
