In an experiment in which a die was thrown110 times, the number of times each face came up was as follows: Face 1 Face 2 Face 3 Face 4 Face 5 Face 6 13 24 16 11 13 33 Calculate the goodness-of-fit test statistic for a test of the fairness of the die, using the formula . State, giving your reasons, how many degrees of freedom the test statistic has, check it for significance at the 5% level and state your conclusions.
