S1 Jan 2001 1) The students in a class were each asked to write down how many CDs they owned. The student with the least number of CDs had 14 and all but one of the others owned 60 or fewer. The remaining student owned 65. The quartiles for the class were 30‚ 34 and 42 respectively. Outliers are defined to be any values outside the limits of 1.5(Q3 – Q1) below the lower quartile or above the upper quartile. On graph paper draw a box plot to represent these data‚ indicating clearly any outliers
Premium Random variable Normal distribution Probability theory
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

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.

far as to say that everyone has a mental illness. However‚ I would feel comfortable saying most people experience a mental illness at some point in their life. I don’t think the word “normal” really even has a meaning. My normal is different than someone else’s normal and the two different types of normal should not be compared. As I said before I do not think everyone in the world has a mental illness‚ but I do think nearly everyone does have a mental illness as some point in their life. With that

Setting a price for a service or product can be very difficult. Patients are now checking to see prices on certain non-emergent services before having them performed. Patients also check prices on medications before they have prescriptions filled. What are the different methods and seven steps for setting an initial price for a product or service?

What is Normal? Lorber’s Believing is Seeing: Biology as Ideology In her article Believing is Seeing‚ Judith Lorber writes of the very fine line between gender and sex. She argues that neither sex nor gender is a pure category of classification. They are more so just a combination of the two of them in the social construction of gender statuses. Her article uses sports and technological competence to show how society transforms physiological differences into gendered social bodies. Lorber’s perspective

Normal psychology is the study that gives focus on the normal or average human behavior according to the socially acceptable behaviors‚ practices and traits.
