Answer:
A point estimate for the true population proportion is and the 90% confidence interval is (0.8025, 0.8575)
Step-by-step explanation:
We have a large sample of people of size n = 506. Let X be the random variable that represents the number of adults who feel that education is one of the top issues facing California. We are interested in the unknown true proportion p of adults who feel that education is one of the top issues facing California. A point estimate for the true population proportion is given by = X/n = 418/506 = 0.83, the standard deviation is given by . Therefore, the 90% confidence interval for the true population proportion is , i.e., , i.e., , (0.8025, 0.8575).
