Question

Records of randomly selected births were obtained and categorized according to the day of the week (see below) that they occurred (based on data from the National Center for Health Statistics). Because babies are unfamiliar with our schedule of weekdays, a reasonable claim is that births occur on different days with equal frequency. Use a 5% significance level to test that claim.
