Use the following to answer the questions below:

In a recent Gallup survey of 1,012 randomly selected U.S. adults (age 18 and over), 53% said that they were dissatisfied with the quality of education students receive in kindergarten through grade 12. They also report that the "margin of sampling error is plus or minus 4%."

What is the population parameter of interest, and what is the correct notation for this parameter?

=proportion of U.S. adults who are dissatisfied with the quality of education students receive in kindergarten through grade 12

= proportion of the sample of 1,012 randomly selected U.S. adults who are dissatisfied = 0.53

p = proportion of U.S. adults who are dissatisfied with the quality of education students receive in kindergarten through grade 12

p = proportion of the sample of 1,012 randomly selected U.S. adults who are dissatisfied = 0.53
