Great Britain has a great literary tradition that spans centuries. One might assume, then, that Britons read more than citizens of other countries. The British Literacy Committee claims that 90% of their citizens read at least one book per month.

Is this sufficient evidence that the true proportion is LOWER than 90%? a. (PS 8.1) Test an appropriate hypothesis and state your conclusions.
