According to a recent article in USA Today, Americans spend $484 per year on alcoholic beverages. As a market research firm for a local wine distributor, you have accessed data on a random sample of 150 Boston residents to see if their spending is higher than average, and perhaps a good area for your client to make a local investment. The average spending in the sample is $404, with a standard deviation of $102. Does this represent a significant difference? Determine this using a 95% confidence level.
