8.3 Exercise 53

Avg difficulty 2.5


Use the following information to answer the next three exercises: According to a Field Poll, 79% of Georgia adults (actual results are 400 out of 506 surveyed) feel that “education and our schools” is one of the top issues facing the state. We wish to construct a 90% confidence interval for the true proportion of Georgia adults who feel that education and the schools is one of the top issues facing Georgia.

A point estimate for the true population proportion is:

  1. 0.90
  2. 1.27
  3. 0.79
  4. 400
