Read the labels. If the label lists sugar, sucrose, fructose, corn syrup, white or âwheatâ flour, they contain simple carbohydrates. If these ingredients are at the top of the list, they may contain mostly simple carbohydrates, and little else. They should be avoided.
A T-wave is a component of an ECG test. It signifies the repolarization of the heart ventricles after a contraction. In the adjacent image, the T-wave is the hump on the right. Every time your heart beats, the muscle is depolarized by an electrical current that originates in the sinoatrial node of the heart.
Instructor: Orin Davis. T-tests are used to compare two means to assess whether they are from the same population. T-tests presume that both groups are normally distributed and have relatively equal variances. The t-statistic is distributed on a curve that is based on the number of degrees of freedom (df).
