Trump Attacks Syria
(CNN)The United States launched a military strike Thursday on a Syrian government airbase in response to a chemical weapons attack that killed dozens of civilians earlier in the week. On President Donald Trump's orders, US warships launched 59 Tomahawk cruise missiles at the airbase that was home to the warplanes that carried out the chemical attacks, US officials said.
Six people were killed in the airstrike, according to a televised statement by the Syrian's Armed Forces General Command. Russia condemned the strike as an "act of aggression." "Tonight, I ordered a targeted military strike on the air field in Syria from where the chemical attack was launched," Trump said during short remarks to reporters at Mar-a-Lago, where he ordered the strike just hours earlier. "It is in this vital national security of the United States to prevent and deter the spread and use of deadly chemical weapons."
The strike took place at 8:40 p.m. ET (3:40 a.m. local time), when there would have been minimal activity at the base. It targeted aircraft, aircraft shelters, petroleum and logistical storage, ammunition supply bunkers, air defense systems, and "the things that make the airfield operate," Pentagon spokesman Capt. Jeff Davis told reporters. The missiles were launched from warships in the Eastern Mediterranean.
Specific Hypothesis and Results
The GCP hypothesis was set for 6 hours beginning at 03:00 local time in Syria. This includes some time before and several hours after the attack. The result is Chisquare 21211.029 on 21600 for p = 0.970 and Z = -1.879.
The following graph is a visual display of the statistical result. It shows the second-by-second accumulation of small deviations of the data from what’s expected. Our prediction is that deviations will tend to be positive, and if this is so, the jagged line will tend to go upward. If the endpoint is positive, this is evidence for the general hypothesis and adds to the bottom line. If the endpoint is outside the smooth curve showing 0.05 probability, the deviation is nominally significant. If the trend of the cumulative deviation is downward, this is evidence against the hypothesis, and is subtracted from the bottom line.

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.
