1. (12 points) In this recession‚ yours truly would like to make extra money to support his frequent filet-mignon-et-double-lobster-tail dinner habit. A promising enterprise is to mass-produce garnet wedding rings for brides. Based on my diligent research‚ I have found out that women’s ring size normally distributed with a mean of 6.0‚ and a standard deviation of 1.0. I am going to order 5000 garnet wedding rings from my reliable Siberian source. They will manufacture ring size from 4.0‚ 4

Statistical mechanics or statistical thermodynamics[note 1] is a branch of physics that applies probability theory‚ which contains mathematical tools for dealing with large populations‚ to the study of the thermodynamic behavior of systems composed of a large number of particles. Statistical mechanics provides a framework for relating the microscopic properties of individual atoms and molecules to the macroscopic bulk properties of materials that can be observed in everyday life‚ therefore explaining

This is statistically significant at the 5% level of significance. The two-sided p-value is .0274 + .0274 = .0548 which is not significant at the 5% level of significance.

Essay 3 This essay provides an analysis of the variables‚ statistical tests and methods used in the assigned research paper. The level of significance and the strengths and limitations of the data collection process were also reviewed. This study had several variables. One major independent variable is the qualitative questionnaire that was verbally given. In this scenario the dependent variable would be the measurement of the data that was collected. The process of a cause-effect relationship

Statistical Analysis The analysis of the data from the study of Barnes & Noble stores is in two stages‚ the descriptive study and inferential statistical study. Initially‚ the Team will distribute and collect the questionnaires. The use of classification will summarize the data and express it in the tabular form for better understanding of the data. For example‚ if the questionnaires consist of information from males and females‚ the data is putinto two categories and expressed

Discuss each aspect of these results. Answer F-value shows significance between the two groups. The null hypothesis should be rejected because the P-Value is 0.005 which would mean that the groups are different. 2.
