Summary
According to the research, the proposed relationship between the response variable and the set of predictors is statistically reliable and can be useful when the research objective is either prediction or explanation. We observe that the F-computed is 257.6> 1.88260439 (F-critical)…

b) Estimate two human capital earnings models, one for men and one for women. Use wage as the dependent variable and include exp, exp2, Educ, not grad, hs grad somepse, uni1, uni2, and marras independent variables. Discuss the goodness of the of the two equations.
From the regression table, we observe that the F-computed is 257.6> 1.88260439 (F-critical), we thus reject the null hypothesis that all regression coefficients are equal to zero. This shows that F-test is significant indicating that the observed R-squared is reliable, and is not a spurious result of oddities in the data set. Also, it shows that the proposed relationship between the response variable and the set of predictors is statistically reliable, and can be useful when the research objective is either prediction or explanation.
From the regression table, we observe that the F-computed is 356.47> 1.88266598 (F-critical), we thus reject the null hypothesis that all regression coefficients are equal to zero. This shows that F-test is significant indicating that the observed R-squared is reliable, and is not a spurious result of oddities in the data set. Also, it shows that the proposed relationship between the response variable and the set of predictors is statistically reliable, and can be useful when the research objective is either prediction or explanation.
c) Interpret the results of the test of overall significance for each equation. Do not forget to state the decision rule for the test, the level of significance you are using, and the critical value of the test statistic.
The p-value for the overall model is 0.0000, a value less than 5%, we thus reject the null hypothesis. The null hypothesis states that the coefficient is equal to zero (no effect). We, therefore, conclude that the model is appropriate and that there is the significant effect on the dependent variable (sewage) by the independent variables.  ...Download file to see next pagesRead More

Variance Report

...? Variance Report Variance Report The key factors to consider when writing the variance report would be the determination of the trends in expenditure within the firm. I would provide a detailed report of the sequence of expenditure items in the financial periods leading up to the point in time when salaries were high and the supplies low. This report would include specific details about the extraneous expenditure items and the miscellaneous items that would have influenced the wage bill within the organization. The determination of the impact of these items would provide a logical explanation of the causative factors within the expenditure bracket. Usually, structural...

Wilkerson Company Variance Analysis

...to be completed in 0.5 hours (or 30 minutes), and after analyzing the data we can find that it is consistent with the actual data, for valves. This means that highest degree of efficiency is being maintained in machine processes. Similarly, same degree of efficiency is being maintained in the production of pumps and flow-controllers. This shows that there is been absolutely no variance among the actual and budgeted financial indicators, and the company is doing well here. Wilkerson management is also using the direct material very efficiently and there's no direct material usage variance. Now, let's look at the gross profit margin of products that are produced by Wilkerson Company. In...

Computing: user requirement specification

...INTRODUCTION: A prototype is the first or original example of something that has been or will be copied or developed. It is a model or preliminary version. Virtually all innovative designs emerge in the interplay between two dueling representations: the wish list of specifications that describe and define the new ideas, and the prototypes that attempt to embody them. A low fidelity prototype is a very basic mock-up or version of the prototype. In this element, I will be discussing the use of low fidelity prototypes for designing a system, as required according to the case study, for managing class attendance. LOW FIDELITY PROTOTYPES: A low fidelity prototype is a prototype that is sketchy and incomplete, that has some...

Variance Analysis

...X592 (Zimmerman, 2014). Each piece requires 4 hours to produce. The standard usage for the 120 pieces is: 4hours x 120 pieces, 480 hours. If the greenhorn production department staff actually uses 490 hours to produce the 120 pieces of the Cyborg product model, there is an unfavorable labor efficiency variance of 10 hours (490 actual hours used less 480 standard hours prescribed). On the other hand, the same company’s expert production staff employees are able to complete the 120 cyborg product model at only 3.85 hours per cyborg product model. The company is able to generate a favorable labor efficiency variance of: (4 hours – 3.85 hours) x 120 pieces, 18 hours. The total actual hours...
