Explanation / Answer

In a Harris poll, adults were asked if they are in favor of abolishing the penny. Among the responses, 1264 answered no, 475 answered yes, and 371 had no opinion.

Total number of responses= 1275+ 475+ 371=2110

Sample size n= 2110

Among 2110 , 475 of them possess the attribute. Among the 2110 , 475 of them said YES. n=2110, x=475

Sample proportion of yes responses = x/n= 475/2110= 0.225

P= x/n= 0.225

The notation of sample proportion is P

ANSWER IS (C) P=0.225
