Suppose we are conducting a chi-squared goodness of fit test to test if a data set follows a uniform(0,16) distribution. We gather 30 observations and decide to use 5 equal probability intervals of the form: [a0, a1], [a1, a2],[a2, a3],[a3, a4],[a4, a5] We find our intervals, and find our test statistic to be 9.21. If we conduct our test using α = 0.05, would we a) Reject the null hypothesis b) Fail to reject the null hypothesis SHOW WORK
