An educational group claims that teaching fraction concepts using math manipulatives results in higher student achievement and understanding of fraction than teaching fractions without the use of any math manipulatives. A teacher in a middle school taught a unit on fractions to two sixth grade classes, one using math manipulatives and the other without the use of an manipulatives. The table below shows the performance of these two classes on a unit test on fractions. Assume the conditions were already met.

With manipulatives: 85, 75, 83, 87, 80, 79, 88, 94, 87, 82

Without manipulatives:78, 84, 81, 78, 76, 83, 79, 75, 85, 81

Test the claim that students who use manipulatives show higher achievement on a test of fractions. Give appropriate statistical evidence to support your answer.
