5. Statistical Abstracts (117th edition) reports that the average amount spent
annually for food by householders under 25 years of age is $2,690. A random
sample of 16 people under 25 years of age who live in a university neighborhood
were surveyed. The survey showed that they spent a sample mean amount of
$3,220 with sample standard deviation $750. Test the claim that the mean for
this neighborhood is different from the national average. Use a 5% significance
level. Assume our data is normally distributed.
