The E, expected count for the five categories, i = 1, 2, 3, 4, 5, is the same as E₁ = 60. The O, observed counts can be found in the data table below along with the expected counts. Use this information to compute the X² test statistic, rounded to two decimal places.

Since the data has been classified into five categories, k = , the degrees of freedom for this test statistic is df = 4.
