From CBC News:
Dozens of grieving Christians attended mass at the Saints
Church in Egypt's Mediterranean port city of Alexandria on
Sunday, the day after 21 worshippers were killed there in an
apparent suicide bombing.
The service was marked by the grief and anger felt by a
congregation devastated by the attack, which took place
outside the church's door about 30 minutes into the new year
as churchgoers were leaving.
Hans Wendt alerted me to the tragedy, suggesting that it
would have powerful repercussions. I set a GCP event for
three hours beginning at midnight, local time, which was
about 30 mins before the bombing.
The result is Chisquare 10706.886 on 10800 df, for p = 0.736
and Z = -0.631
It is important to keep in mind that we have only a tiny
statistical
effect, so that it is always hard to distinguish signal from
noise. This means that every "success" might be largely
driven by chance, and every "null" might include a real
signal overwhelmed by noise. In the long run, a real effect
can
be identified only by patiently accumulating replications of
similar analyses.
