-- Students of mathematics in a large university are given a percentage mark in their annual examination. In a sample of nine students the following marks were found: 28 32 34 39 41 42 42 46 56 Students of history also receive a percentage mark. A sample of five students reveals the following marks: 53 58 60 61 68 Do these data support the hypothesis that the marks for mathematics are more variable than the marks for history?
