Clаrk cоllects sneаkers, аnd Maria cоllects whiskey. Bоth products can see a large difference in the retail price and the price on the secondary market. Maria believes that the difference is greater for whiskey, and Clark believes it is greater for sneakers. In order to settle the argument, both Clark and Maria randomly select a sample of their collections, and record the difference in retail and secondary market prices.

Based on a sample of 34, Maria finds an average difference of 167.0% with a standard deviation of 23.5%. Use hypothesis testing to try to settle the debate between Clark and Maria at the 10% significance level. State the conclusion of the test, and explain your answer.
