In a publication of a well-known magazine, it is stated that
automobiles travel in average at least 20,000 kilometers per year,
but do you think the average actually is minor. To test this claim,
a sample of 100 car owners is asked randomly selected to keep a
record of the kilometers they travel. It would If you agree with
this statement, if the random sample indicates an average of 19,000
kilometers and a standard deviation of 3900 kilometers? Use a
significance level of 0.05 and for its engineering conclusion use:
a) The classical method. b) The P-value method as an auxiliary.
