Question

Test the following claims. This process should include each step as outlined
in the text:

The literacy rate is defined to be the proportion of people over 15 years of age who
can read. The literacy rate in the United States is 97%. This is very high, but some
countries appear to be doing even better. For example, the rate in Japan appears
to be higher than 97%. Suppose we gather a sample of 450 Japanese people over 15
years of age, and of these, 445 can read. Test the claim at 1% significance that the
literacy rate in Japan is higher than the U.S. literacy rate of 97%. (The proportions
from this sample are based on statistics given in the CIA World Factbook).
