At the Statistics Canada Web site, you can find the percent of adults in each province or territory who have at least a university certificate, diploma, or degree at bachelor's level or above.
It makes no sense to find x bar for these data and use it to get a confidence interval for the mean percent u in all 13 provinces or territories. Why not?

You need to weight the provinces for province population first. Some of them are very sparsely populated.
