In 2008, Malcolm Gladwell released his book Outliers. In the book, Gladwell claims that more hockey players are born in January through March than in October through December. The following data show the number of players selected in the 2010 National Hockey League draft according to their birth month. Is there evidence to suggest that hockey players’ birthdates are not uniformly distributed throughout the year? Use the a = 0.05 level of significance.

Birth Month                                 Frequency

January–March .............................     63

April–June .....................................      56

July–September ...........................      28

October–December .....................     34
