According to AARP, in 2008, 49% of all annual expenditure on restaurant food was by Americans age 50+. In fact AARP claims the average annual expenditure for Americans age 50+ on restaurant food in 2008 was $1960. Suppose a 2015 study randomly sampled 42 Americans age 50+ and found an average annual expenditure on restaurant food of $2145 with a standard deviation of $600. Is there reason to believe that the average annual expenditure for Americans age 50+ on restaurant food has increased since 2008 at α=.025?
