In a Harris poll, adults were asked if they are in favor of abolishing the penny. Among the responses, 1236 answered "no," 496 answered "yes," and 379 had no opinion.

 

What is the sample proportion of yes responses, and what notation is used to represent it?

Answer 1

add the 3 given numbers then divide 1236 by that sum to get the proportion

yes/total= y/(y+n+u) = the percentage of proportion of yes responses = about 58.55%
