Great Britain has a great literacy tradition that spans centuries. One might assume, then, that Britons read more than citizens of other countries. Some Canadians however, feel that a higher percentage of Canadians than Britons read. A recent random sample found that 912 of 1012 randomly selected Candaians read at least one book per year, compared to 785 of 968 randomly selected Britions. Find a 90% confidence interval for the difference in the proportion of Britons and Canadians who read at least one book a year.
