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(0.4772) = 0.9554 Therefore the probability that a measurement selected at random will be between 19 and 31 is about 0.95. This area (probability) is shown fir the X values and for the z values. σ = 3 0.95 σ =

said‚ we reject the null hypothesis and accept the alternative because some of the plants in the pot with the larger amount of seeds did not even start to grow. All of the plants in the groups with 5 seeds at least grew. This indicates that dependent variables such as competition and the environment itself has an influence on how a plant grows and develops. If the T-Stat>T-Critical‚ then we reject the null hypothesis and choose the alternative. The only one we actually accept the null hypothesis

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

Is an average age-equivalent comparison acceptable when comparing a 19 year-old to a 14 year-old or 22 year-old? The answer to the opening question is the basis of this article response paper. Emily Maloney and Linda Larrivee discuss age-equivalent (AE) scores within their article titled‚ “Limitation of Age-Equivalent Scores in Reporting the Results of Nor-Referenced Test.” Speech-language pathologists (SPLs) should not use AE scores based on the list of limitations found in the author’s findings

CHAPTER 8. TRIP DISTRIBUTION NPTEL May 3‚ 2007 Chapter 8 Trip distribution 8.1 Overview The decision to travel for a given purpose is called trip generation. These generated trips from each zone is then distributed to all other zones based on the choice of destination.

There are a number of methods to distribute trips among destinations; and two such methods are growth factor model and gravity
