Normal Distribution It is important because of Central Limit Theorem (CTL)‚ the CTL said that Sum up a lot of i.i.d random variables the shape of the distribution will looks like Normal. Normal P.D.F Now we want to find c This integral has been proved that it cannot have close form solution. However‚ someone gives an idea that looks stupid but actually very brilliant by multiply two of them. reminds the function of circle which we can replace them to polar coordinate Thus Mean

decimal places) 2. Find the value of z if the area under a Standard Normal curve a) to the right of z is 0.3632; b) to the left of z is 0.1131; c) between 0 and z‚ with z > 0‚ is 0.4838; d) between -z and z‚ with z > 0‚ is 0.9500. Ans : a) z = + 0.35 ( find 0.5- 0.3632 = 0.1368 in the normal table) b) z = -1.21 ( find 0.5 – 0.1131 = 0.3869 in the normal table) c ) the area between 0 to z is 0.4838‚ z = 2.14 d) the area to the

VI. Results and Discussion In this exercise‚ the goal was to produce acetylsalicylic acid through the organic synthesis from the reaction of salicylic acid to acetic anhydride‚ the starting materials. Instead of using acetic acid‚ acetic anhydride was used as solvent since the anhydride reacting with water to form acetic acid tends to drive the reaction to the right. It results from the elimination of a molecule of water from two molecules of acetic acid (see Fig. 11.2). Figure 11.3 below

Normal psychology is the study that gives focus on the normal or average human behavior according to the socially acceptable behaviors‚ practices and traits. In contrast‚ abnormal psychology is the study that deals with unusual human behaviors that people deem are against the socially accepted behaviors and that includes mental disorders. Differentiating the two however‚ needs careful study because it involves human judgment which may or may not be necessarily correct. To aptly define and contrast

Anger Management as a Behavioral Modification Baseline Phase Report Jessica T. Van Nostrand Liberty University Analysis of Target Behavior To help define my behavior I asked my brother for help. Below are the agreed upon behaviors that I exhibit at a particular time. I am hoping that this qualifies for an IOA (interobserver agreement or interobserver reliability). When I observe something that my brother (age 66) has either done or not done that displeases me‚ my voice gets very

Metabolic Acidosis Metabolic acidosis is a condition in which there is too much acid in the blood. It happens because of a chemical imbalance in your cells. Metabolic acidosis can happen at any age‚ and there are many different causes. It may be a symptom of a sudden‚ short-lived (acute) condition‚ or a lifelong (chronic) condition. Metabolic acidosis can be mild‚ or it can be severe and life-threatening‚ depending on the cause. It can be corrected if the cause is identified and treated correctly

Normal Distribution Normal distribution is a statistics‚ which have been widely applied of all mathematical concepts‚ among large number of statisticians. Abraham de Moivre‚ an 18th century statistician and consultant to gamblers‚ noticed that as the number of events (N) increased‚ the distribution approached‚ forming a very smooth curve. He insisted that a new discovery of a mathematical expression for this curve could lead to an easier way to find solutions to

Baseline Project Plan Report 1.0 Introduction A. Project overview- Project scope: We will contract yearly with university to create wiring network of PCs in laboratory for students with 60 PCs and maintenance it during 5 year. Justification: we want to make the interface between students and staff and between the students themselves more easily and usefully. Recourse requirement: to make this network I need 60 computer‚ cables and switches‚ server for the internet tables and chare. Schedules:

Normal Distribution:- A continuous random variable X is a normal distribution with the parameters mean and variance then the probability function can be written as f(x) = - < x < ‚ - < μ < ‚ σ > 0. When σ2 = 1‚ μ = 0 is called as standard normal. Normal distribution problems and solutions – Formulas: X < μ = 0.5 – Z X > μ = 0.5 + Z X = μ = 0.5 where‚ μ = mean σ = standard deviation X = normal random variable Normal Distribution Problems and Solutions – Example
