A population of measurements is approximately normally distributed with mean of 25 and a variance of 9. Find the probability that a measurement selected at random will be between 19 and 31. Solution: The values 19 and 31 must be transformed into the corresponding z values and then the area between the two z values found. Using the transformation formula from X to z (where µ = 25 and σ √9 = 3)‚ we have z19 = (19 – 25) / 3 = -2 and z31 = (31 - 25) / 3 = +2 From the area between z =±2 is 2(0

Refractive index measurement is actually a measurement of the speed of light in a medium. The speed of light (usually denoted by c) is 299 792 458 m/s in vacuum. In other media the speed of light is lower than this value‚ and the refractive index‚ R.I.‚ of a medium is a measure of how much the speed of light is reduced in the medium. The refractive index (n) of a medium is defined as the ratio of speed of light in vacuum (c) in to that in the medium (v) The speed of light in a medium depends on

Condom Distribution to Teens Over the past 30 years‚ condom distribution has not effectively helped against sexually transmitted diseases (STD) or teen pregnancies because condoms are used incorrectly or not at all. The question remains: does it encourage teens to engage in sex by pushing condoms in their hands? We will explore the effectiveness of the program‚ taxpayer views‚ and religious views. The theory generally accepted in justifying the distribution of condoms to teenagers is that this

Everyone ultimately has one common desire; to achieve happiness. In Kohn’s essay‚ “How Not to Get Into College: The Preoccupation with Preparation” and in Heron Jones poem‚ “Somnambulist” they discuss that individuals are not achieving happiness because they rely on extrinsic motivators to produce intrinsic happiness. Kohn and Jones argue that people use extrinsic motivators to provide intrinsic happiness for themselves without knowing the toll they are carrying; instead people should tend to follow
