A student used just one trade publication to price desktops that have at least a 20 GB hard drive and a 700 MHz processor speed. To justify relying on the one source, he took a sample of prices for such systems, as quoted in dealers' ads in the publication. Assume the industry mean price for such a system is $1750. Use a 0.01 significance level to test the claim that the mean quoted price in the sample is no different from the industry average of $1750. Interpret the results from this table.
