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).

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.
