Question

Based on information in Statistical Abstract of the
United States, the avg annual miles driven per
vehicle in the US is 11.1 thousand miles. Suppose that
a random sample of 36 vehicles owned by residents of
Los Angeles showed that the average mileage driven last
year was 10.8 thousand miles with standard deviation
600 miles (watch the units!). Does this indicate that
the average miles driven per vehicle in Los Angeles is
different than the national average? Use a 0.05 level
of significance.

How coould this be solved using a Ti84 calculator?
