Question

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

1236/(1236 + 496 + 379) = 1236/1732+379 = 1236/2111= about 58.55%

= y/(y+n+u)
