Secession In Example 6.4 on page 360 we analyzed a poll of 800 Quebecers, in which 28% thought that the province of Quebec should separate from Canada. Another poll of 500 Texans found that 18% thought that the state of Texas should separate from the United States.

(a) In the sample of 800 people, about how many Quebecers thought Quebec should separate from Canada? In the sample of 500, how many Texans thought Texas should separate from the US?

(b) In these two samples, what is the pooled proportion of Texans and Quebecers that want to separate?

(c) Can we conclude that the two population proportions differ? Use a two-tailed test and interpret the result.
