A question from my stats class:

"Births are not, as you might think, evenly distributed across the days of the week. Here are the average numbers of babies born on each day of the week in 2003:

Day Births
Sunday 7,563
Monday 11,733
Tuesday 13,001
Wednesday 12,598
Thursday 12,514
Friday 12,396
Saturday 8,605

Suggest a reason why there are fewer births on weekend days than during the week."

What the freak? What am I, a flippin doctor? I thought this was a statistics class, not an obstetrics class.

So here was my BS answer:
"When pregnant women move around a lot it can cause an early birth. Perhaps there are many working women who are up on their feet all day and go into labor because of it. So because most work weeks are Monday through Friday, it would make sense to have a birth on a working day than a weekend resting day."

Is that even true? Let's hope the TA that grades this believes me.

Its because Doctors don't work on weekends. They'll induce early, or have the woman wait until monday.


We had a similar question in my stats class.
