A variable contains five categories. It is expected that data are uniformly distributed across these five categories. To test this, a sample of observed data is gathered on this variable resulting in frequencies of 27, 30 29, 21, and 24. Using a = .01, the appropriate decision is - O reject the null hypothesis that the observed distribution is uniform reject the null hypothesis that the observed distribution is not uniform O do not reject the null hypothesis that the...
