You must not to combine foods rich in protein (meat, curd, milk) with rich carbohydrates (flour products, potatoes).
The Critical Value. The critical value for our margin of error formula is denoted by zÎ±/2. This is the point z* on the standard normal distribution table of z-scores for which an area of Î±/2 lies above z*. Alternately is is the point on the bell curve for which an area of 1 - Î± lies between -z* and z*.
The method of least squares. The r.m.s. error for the regression line of y on x is: The regression equation is the equation for the line that produces the least r.m.s. error or standard error of the estimate. If x and y are perfectly related, that is all points lie on the regression line, the standard error of estimate is zero (the square root of 1 - 12 = 0), there is no deviation from the line.
