It could refer to four standard errors. If an observation from a Gaussian (normal) distribution is 4 standard errors away from the mean, it has an extremely low probability.

Well, darling, Sigma Sigma Sigma was created on April 20, 1898 at Longwood University in Farmville, Virginia. So, if you're ever on a game show and they ask you that question, you can thank me later for making you look like a smarty pants.
Methane has tetrahedral geometry. In methane carbon undergoes sp3 hybridisation. The four sp3 hybrid orbitals form four sigma bonds with four 1s orbitals of hydrogen atoms.
Sigma Mu Sigma was definitely at Lynchburg College between 1968-1972.
No, 99.999 is not a 3 sigma limit; it corresponds to a 5 sigma limit. In a normal distribution, a 3 sigma limit encompasses approximately 99.73% of the data, while a 5 sigma limit includes about 99.99994%. Therefore, a 5 sigma level indicates a much lower probability of error compared to a 3 sigma level.
DMSS is Design and Manufacturing Six Sigma, they offer the full four week course.
Four sigma bonds. One between the carbon and each hydrogen in turn.
CH2Cl2 Four sigma bonds as the central carbon is bonded covalently to two hydrogens and two chlorine's.
Six Sigma levels refer to the performance metrics used to measure process quality and efficiency. The term "Six Sigma" itself represents a quality level where only 3.4 defects occur per million opportunities, indicating near perfection. The levels can be categorized as follows: one sigma (690,000 defects per million), two sigma (308,537), three sigma (66,807), four sigma (6,210), five sigma (233), and six sigma (3.4). Each level signifies a progressive improvement in process reliability and reduction of variability.
In C6H12, each carbon atom forms four sigma bonds, and hydrogen forms one sigma bond. Since there are 6 carbon atoms and 12 hydrogen atoms present, the total number of sigma bonds would be (6 carbon atoms x 4 sigma bonds per carbon) + (12 hydrogen atoms x 1 sigma bond per hydrogen) = 24 + 12 = 36 sigma bonds.
Sigma Sigma Rho was created in 1998.
The XeO4 molecule uses sp3 hybrid orbitals from xenon for sigma-bonding. This allows xenon to form four sigma bonds, each with one oxygen atom in XeO4.
The hybridization of Cl in ClO4- is sp3. It forms four sigma bonds with the four oxygen atoms, resulting in a tetrahedral molecular geometry.

There is a double bond between the two carbons, so that is one sigma bond and one pi bond. The hydrogen's all are sigma bonded to the carbons so there are four sigma bonds there. So, there is one pi bond overall and five sigma bonds overall.
Sigma Mu Sigma was created on 1921-03-25.
Kappa Sigma Sigma's motto is 'A kappa sig nunquam mendums'.
