According to the document Consumer Expenditures, a publication of the Bureau of Labor Statistics, the average consumer unit spent $1874 on apparel and services in 2006. That same year, 25 consumer units in the Northeast had the following annual expenditures, in dollars, on apparel and services.
At the 5% significance level, do the data provide sufficient evidence to conclude that the 2006 mean annual expenditure on apparel and services for consumer units in the Northeast differed from the national mean of $1874? (Note: The sample mean and sample standard deviation of the data are $2060.76 and $350.90, respectively.)
