In 2014, Nanos Research conducted a survey of 1000 adult Canadians to determine their favourability toward the Alberta oil sands project. The responses were "favourable", "somewhat favourable", "somewhat unfavourable", "unfavourable", and "unsure". Grouping "favourable" and "somewhat favourable" together, the percentages vary by geography, gender, and age group and are given in the fileAssign1Data (Tab Q2)

a) Construct 95% confidence intervals for each geographical region and compare them geographically.

b) Construct 99% confidence intervals for the difference the Prairies (where favourability is highest) and the Atlantic provinces (where favourability is lowest) and interpret its meaning.

c) Conduct a similar analysis for the age groups(using sub-questions a&b).

d) Are you 99% confident that there is a difference between men and women?

e) Write a report summarizing what this survey indicates about differences in favourability to the

Alberta oil sands project by geography, gender, and age group.
