Arithmetic Mean and Five-step P-value Approach - 1414 Words

Sample 9.23 A manufacturer of chocolate candies uses machines to package candies as they move along a filling line. Although the packages are labeled as 8 ounces, the 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? (Use a 0.05 level of significance.) B. Determine the p-value and†¦show more content†¦C. Interpret the meaning of the p-value in (b). D. Compare your conclusions in (a) and (b). 9.53 The U.S. Department of Education reports that 46% of full-time college students are employed while attending college (data extracted from â€Å"The Condition of Education 2009,† National Center for Education Statistics, nces.ed.gov). A recent survey of 60 full-time students at Miami University found that 29 were employed. A. Use the five-step p-value approach to hypothesis testing and a 0.05 level of significance to determine whether the proportion of full-time students at Miami University is different that the national norm of 0.46. B. Assume that the study found that 36 of the 60 full-time students were employed and repeat (a). Are the conclusions the same? 9.55 One of the issues facing organizations is increasing diversity throughout the organization. One of the ways to evaluate an organization’s success at increasing diversity is to compare the percentage of employees in the organization in a particular position with a specific background to the percentage in a position with that specific background in the general workforce. Recently, a large academic medical center determined that 9 of 17 employees in a particular position were female, whereas 55% of the employees for this position in the general workforce were female. At the 0.05 level of significance, is there evidence that the proportion of females in this position at thisShow MoreRelatedAn Enhanced Graphical Password Scheme Using Aonv Essay2196 Words   |  9 Pagespresented a graphic-based password scheme using Arithmetic Operators and Numerical Value (AONV) in which the aforementioned issues are addressed. The AONV model consists of registration and verification stages which users must successfully complete in order to be authenticated. A hybrid technique based on recognition, cued and pure recall was adopted. The system security was enhanced by image matching, numerical value, computational numeric secret key, arithmetic operator and shuffling of images in gridRead MoreStrategic Asset Allocation: Determining the Optimal Portfolio with Ten Asset Classes11012 Words   |  45 Pagesexplores which asset classes add value to a traditional portfolio of stocks, bonds and cash. Next, we determine the optimal weights of all asset classes in the optimal portfolio. This study adds to the literature by distinguishing ten different investment categories simultaneously in a mean-variance analysis as well as a market portfolio approach. We also demonstrate how to combine these two methods. Our results suggest that real estate, commodities and high yield add most value to the traditional assetRead MoreInstrumentation in Mathematics8575 Words   |  35 PagesFind th e length of the third side of each triangle 84 Find the distance between the points 85-86 On Statistics Introduction 87 Tally 88 Arrange in Ascending Order and Find the Range 89 Finding the Mean of a Data Set 90 Calculating the Mean, Median, Mode and Range 91 Calculating Mode 92 Calculating the median of a Data Set 93 Frequency 94 Calculate the first, second, and third quartile for each Data Set 95 On Probability DeterminingRead MoreStatistical Data Analysis For The Field Of Nursing2208 Words   |  9 Pages LITERATURE EVALUATION Julian Fils Thomas Edison State University LITERATURE EVALUATION Statistical data analysis is the foundation of every research; it is the first step in and a research and is the part that helps researcher developed results.

The Board consists of five members who serve for five year staggered terms. Only firms that have registered with the Board are able to audit publicly-quoted companies. This gives the Board new and significant monopoly powers. It is also responsible for creating, promulgating and monitoring standards of auditing and of ethical behavior.

In addition, outlining the course that got us to where we are today, trying to determine what it means to understand something and how understanding can be assessed assists us in continuing that course of action in the right direction. In 1980, recommendations were made by the National Council of Teachers of Mathematics for reforming mathematics
