z score 98

This is a very important concept. Earlier we said a probability depends on what you define as favorable event. Some times a favorable event of z times is defined as a function related to the actual score of x, the mean of the scores m and the standard deviation of s of a data. They are related as, z..

Varieties of test scores

." But ranking method can be misleading also because in ranking scores no account is taken of unequal intervals between the scores. The one-point difference between successive ranks may represent very different intervals between the scores. Thus,, the scores 60, 50, 49, 46, 25, 20 which are quite unevently s..

monoglycerides b. It split large fat in to small particles so as to increase the surface area for lipase action c. Micelle - Tryglycerides + bile salts After the action of lipase the micelles converted in to monoglycerides and force fatty acids together with bile salts. From there micelle microglycecles and free fatty acids alone..

Describing Data Using Statistics

Statics is most popular and important topic in the mathematics. It is commonly used for finding the Mean, Mode and Median for a set of data, to compute Range, Variance and Standard Variation and also help us to understand the means of these. We construct the Box and Whiskers plot with the help of the statics. It creates capable us to compute the..

boiling point at sea level

if the gravitational acceleration g and the ambient temperature T a may be assumed to be constant (e.g. problem 184). Thus if we put T 0 for the boiling point of water at sea level and T z for the boiling point at height z, and p 0 for atmospheric pressure at sea level, we have two expressio..
