According to a poll, 83% of california adults (418 out of 506 surveyed) feel that education is one of the top issues facing california. we wish to construct a 90% confidence interval for the true proportion of california adults who feel that education is one of the top issues facing california.

what is a point estimate for the true population proportion?

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).

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
