From the Washington Post:
A suicide bomber killed at least 48 people in the Afghan capital on Tuesday after detonating explosives outside a packed Shiite mosque as throngs of worshippers observed a religious holiday, police and a government official said.
The noontime explosion outside a prominent shrine in the Murad Khani district of Kabul was a rare attack in a city where insurgents have in recent months targeted mainly Western installations and military personnel.
It was among the deadliest attacks targeting civilians in the decade-long war, and the first major attack on Shiites in Afghanistan since the fall of the Taliban. More than 100 people were injured.
A second blast in the northern city of Mazar e Sharif on Tuesday also appeared to target Shiite worshippers and left at least four people wounded. That bombing sparked clashes between Sunni and Shiite university students, witnesses and security officials said.
The GCP event was set for 6 hours beginning about an hour before the bombing in Kabul.
The result is Chisquare 21489 on 21600 df, for p = 0.703 and X = -0.533.
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.
