Chapter 4, Problem 48SE

English in California Schools This problem concerns the vote of the Ventura County cities on Proposition 227 in June of 1998. Proposition 227 in California stated that children should be taught primarily in English and abolished bilingual education. The statewide vote showed that 61% of the voters were in favor of this proposition. Repotted in the table arc the percentages of voters in each city who voted for Proposition 227 and the percentages of students in those cities with limited English, according to the Ventura County Star.

Assume that the association between the percentage of voters who favor the initiative and the percentage of students with limited English is linear enough to proceed. Find the regression equation for predicting $"\%$ Yes" from $"\%$ Students with Limited English," and report it. Interpret the sign of the slope clearly.
