Are births evenly distributed across days of the week? A random sample of births from a local health department gave the following information.
Day # Births
Sun 3
Mon 7
Tue 12
Wed 10
Thu 9
Fri 11
Sat 2
Total 54
(a) If births are evenly distributed, how many would you expect on each day?
Expected number = (one decimal place)
(b) Would a goodness of fit test be valid in this situation?
___ Yes. The expected count for each day is at least 5, and the sample is random.
___ Yes. The sample size is large enough, and the sample is random.
___ No. There are two days with less than 5 births.
