Guessing the Bounce Plate Affect Abstract The goal behind this experiment was to estimate the distance a ball would travel after it falls a certain distance and bounces off a metal plate which has an angle of 45 degrees. To find this we had to take the basic equations for kinematics which are (1/2)at2=x and v=v0+at and combine them to make an equation that will help us solve for the distance the ball will travel after hitting the bounce plate. The equation came out to be R=g*(sqrt(2)/sqrt(g))*(sqrt(H)*sqrt(h))

Week Five Discussion | This Discussion will give you the opportunity to calculate or identify the three measures of central tendency. You will be asked to select an appropriate real life situation in which one measure would be more appropriate than the other two measures of center. 1. Select a topic of interest to you and record the topic in your posting‚ for example: “What is the average number of hours people watch TV every week?” Make sure the question you ask will be answered with a number

Measuring Service Quality Using SERVQUAL Introduction Measuring the quality of a service can be a very difficult exercise. Unlike product where there are specific specifications such as length‚ depth‚ width‚ weight‚ colour etc. a service can have numerous intangible or qualitative specifications. In addition there is there expectation of the customer with regards the service‚ which can vary considerably based on a range of factors such as prior experience‚ personal needs and what other people

company wants the packages to contain a mean of 8.17 ounces so that virtually none of the packages contain less than 8 ounces. A sample of 50 packages is selected periodically‚ and the packaging process is stopped if there is evidence that the mean amount packaged is different from 8.17 ounces. Suppose that in a particular of 50 packages‚ the mean amount dispensed is 8.159 ounces‚ with a sample standard deviation of 0.051 A. Is there evidence that the population mean amount is different from 8.17 ounces

1 “Arithmetic vs. Geometric Means: Empirical Evidence and Theoretical Issues” by Jay B. Abrams‚ ASA‚ CPA‚ MBA Copyright 1996 There has been a flurry of articles about the relative merits of using the arithmetic mean (AM) versus the geometric mean (GM). The Ibbotson SBBI Yearbook took the first position that the arithmetic mean is the correct mean to use in valuation. Allyn Joyce’s June 1995 BVR article initiated arguments for the GM as the correct mean. The previous articles have centered

HONORS STATISTICS CH1 In an observational study‚ researchers simply observe characteristics and take measurements‚ as in a sample survey. In a designed experiment‚ researchers impose treatments and controls and then observe characteristics and take measurements. Data from a sample of citizens of a certain country yielded the following estimates of average TV viewing time per month for all the citizens. Answer: Inferential‚ because the statistics are used to make inference about the

Higher Arithmetic Higher arithmetic‚ also known as the theory of numbers‚ is known for its basics of the natural numbers‚ simple numbers. The numbers‚ 1‚ 2‚ and 3 are numbers that are known as natural numbers. H. Davenport of Cambridge University once said “…in all the records of ancient civilizations there is evidence of some preoccupation with arithmetic over and above the needs of everyday life” (Introduction). The theory of numbers being a science‚ is simply just a creation invented for the
