Analyses of Variance

(Goodness –of-Fit)
Conduct hypotheses test and provide the statistics, critical value, and/ or P-value, and state the
conclusion

Question;
Births: Records of randomly selected births were obtained and categorized according to the day
of the week that they occurred ( based on data from national Center for health Statistics).
Because babies are unfamiliar with our schedule of weekdays, a reasonable claim is that births
occur on the different days with equal frequency. See the table below and use 0.01 significance
level to test that claim. Can you provide an explanation for the result?
