Arithmetic mean

In the book, “Statistical Techniques in Business & Economics,” authors D. Lind, W. Marchal & S. Wathen (2012), describe how to conduct this test of hypothesis. We seek to determine if two sampled populations, females and males, have the same mean (arithmetic average) wages. The process begins with only the raw data from a 2005 wages database. As a result, the authors further explain: “The method described does not require that we know the standard deviations of the populations (2012).” For that

Harris, and Robert C. Higgins “Cost of capital is so critical to things we do, and CAPM has so many holes in it—and the books don’t tell you which numbers to use… so at the end of the day, you wonder a bit if you’ve got a solid number. Am I fooling myself with this Theories on cost of capital

favorable) to 1(e.g. unfavorable). The observed frequencies of each category, however, are counted and being weighted to imply that a greater importance is attached to respondents with certain characteristics of the scale. The arithmetic means produced of scale's categories guide only the analysis and merely generate a directional insight, and do not provide specific numerical magnitude. Our methodology endorses such a rating scale. c) Sample Size and Control The introduced methodology

A researcher must think about the data collection and sample size in the early stages of the research process because it will affect the way the researcher analyzes the data. There are two main reasons a researcher should do it in the early stages. The first one is that the researcher cannot apply just any technique to any variable. The other one is the size and nature of your sample are likely to impose limitations on the kinds of techniques you can use (Bryman 2008). The female researcher wants

Weight Reducers International, advertises that those who join will lose, on the average, 10 pounds the first two weeks with a standard deviation of 2.8 pounds. A random sample of 50 people who joined the new weight reduction program revealed the mean loss to be 9 pounds. At the .05 level of significance, can we conclude that those joining Weight Reducers on average will lose less than 10 pounds? Determine the p-value To calculate the test statistics: Z=(9-10)/(2.8/sqrt(50))= -2.525
