ANOVA Hypothesis Testing Paper
According to Payscale.com an individual with a high school education entering the work force will earn less than an individual with the same level of education who has worked longer in that particular field (Harrison, 2010). Team A has selected data from the Wages and Wage Earners data set and will be using the analysis of variance, also known as ANOVA, to compare the mean of age groups 18 - 63 which were broken down into four age groups to compare the average salary of each age group and will determine the accuracy of Payscale’s claim. In this paper we discuss our research question and the hypothesis and show how we concluded the selected hypothesis. Research Question and Hypothesis Statement

Is there a difference in earned wages for workers with a 12th grade education based on the age of the worker? At a five percent level of significance (α), the team’s null hypothesis (H0) is that the mean scores are the same for the four groups 18-25, 26-33, 36-44, and 46-53. The alternate hypothesis (H1) is that at least one mean is different. These hypotheses are simply illustrated as: H0: πgroup 1 = πgroup 2 = πgroup 3 = πgroup 4, H1: At least one mean is different. Five Steps Hypothesis Testing and Results of F Test

Team A conducted the following steps to test their hypothesis. Step 1 – The null and alternate hypotheses:
H0: πgroup 1 = πgroup 2 = πgroup 3 = πgroup 4 H1: At least one mean is different
Step 2 – Select the level of significance: ά = .05
Step 3 –Identify test statistic:
Use the “F” distribution because this is an ANOVA test Step 4 – Formulate the decision rule
Reject the null hypothesis if F-calculated is greater than 2.85 (F-critical) Step # 5 – Calculate the test statistic, arrive at a decision, and state a conclusion:

ABC’s real estate agency has recently expanded its business and is in the process of conducting research on housing prices within 10 miles of its new office. Team B has been given the task by ABC real estate to conduct the needed research. The team will be able to answer at the end of the research if the prices in Santa Cruz, California, are less than the prices of house in Scott’s Valley, California. Throughout...

* Used to prove which are the factors that are actually impacting the mean or standard deviation of the project y.
* To see the impact of improvements after they are implemented
* P- value is critical in making decisions.
* To determine if the statistical hypothesis is true or false, the entire population should be examined, which becomes impossible for large sizes, Random sampling is done.
* The conclusion for...

...the analysis test result is carried out using the technique of one-way analysis of variance ANOVA (Analysis of Variance - single factor).
Assumptions of ANOVA
The assumptions of ANOVA are: Observations were randomly and independently chosen from the populations, population distributions are normal for each group; and population variances are equal for all groups.
The assumptions of ANOVA are identical to the t-test and...

Inside statistics, it has to be understood what hypothesistesting is to find and verify research to be studied. Hypothesistesting is a form of research that is used to show how a certain issue will end or how the researcher(s) think the issue will end in the environment that it is situated....

Abstract
In this paper, Team A will be determining and discussing how there will be an overall shortage of truck drivers in the years of 2012 and 2014. We will be using a null hypothesis and alternative hypothesis to determine which hypothesis is correct. The subject that is being testing is the issue of a possible decrease in the number...

I learned from the text that hypothesistesting is a “Procedure for deciding whether the outcome of a study (results from a sample) supports a particular theory or practical innovation (which is thought to apply...
