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.

Is 99.999 a 3 sigma limit?

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.


How do you find the correlation of n equals 15 Σxi equals 1293 Σyi equals 48.58 Σxiyi equals 4226.2 sx equals 6.9714 and sy equals 0.4236?

To find the correlation coefficient ( r ), use the formula: [ r = \frac{n \cdot \Sigma x_i y_i - \Sigma x_i \cdot \Sigma y_i}{\sqrt{(n \cdot \Sigma x_i^2 - (\Sigma x_i)^2)(n \cdot \Sigma y_i^2 - (\Sigma y_i)^2)}} ] Given ( n = 15 ), ( \Sigma x_i = 1293 ), ( \Sigma y_i = 48.58 ), ( \Sigma x_i y_i = 4226.2 ), ( s_x = 6.9714 ), and ( s_y = 0.4236 ), first calculate ( \Sigma x_i^2 ) and ( \Sigma y_i^2 ) using the relation ( s_x^2 = \frac{\Sigma x_i^2}{n} - \left(\frac{\Sigma x_i}{n}\right)^2 ) and ( s_y^2 = \frac{\Sigma y_i^2}{n} - \left(\frac{\Sigma y_i}{n}\right)^2 ). After obtaining these values, substitute them into the formula for ( r ) to find the correlation coefficient.
