input: Standard error

The standard error (SE) of a statistic (usually an estimate of a parameter) is the standard deviation of its sampling distribution or an estimate of that standard deviation. If the parameter or the statistic is the mean, it is called the standard error of the mean (SEM).

IN: In 1948, Irma Nydia Vasquez, the first Miss Puerto Rico, became the first Latina contestant. In addition, in 1948, Yun Tau Chee, the first Miss Hawaii, was also the first Asian-American contestant. Miss America 1949, Jacque Mercer, was married and divorced during her reign; after this, a rule was enacted requiring Miss America contestants to sign a certification that they have never been married or pregnant. Starting in 1950, although the pageant continued to be in September, the Miss America title changed to ''post-dated'', thus that year's pageant winner became Miss America 1951, and there was no Miss America 1950. The pageant was first televised nationally in 1954, hosted by Bob Russell. Future television star Lee Meriwether was crowned Miss America 1955. It would also be the last time Russell served as host. He recommended, and was replaced by, Bert Parks, who served as the host for the second televised pageant in 1955 and stayed as host until 1979. Television viewership peaked during the early 1960s, when it was the highest-rated program on American television.

Text: In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NO) emissions reduction technique used in petrol/gasoline and diesel engines. EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders. This dilutes the O in the incoming air stream and provides gases inert to combustion to act as absorbents of combustion heat to reduce peak in-cylinder temperatures. NO is produced in a narrow band of high cylinder temperatures and pressures. Another primary benefit of external EGR valves on a spark ignition engine is an increase in efficiency, as charge dilution allows a larger throttle position and reduces associated pumping losses.

Question: is the egr valve part of the engine?

OPTIONS:
- no
- yes
