Get college assignment help at Smashing Essays Question Sampe size is 34 which are Male=17 and Female 17The readings for this week focus on the concepts of independent-samples t tests and ANOVAs. In this discussion we will apply those concepts to the analysis of a case study. Read the “Animal Research” case study presented in Chapter 20 of the Online Statistics Education text. In the body of your posting, include an overview of the following based on the research question, “Is there a gender difference with respect to the belief that animal research is necessary?”

Create a descriptive statistics table and histogram for selected variables in a

Create a descriptive statistics table and histogram for selected variables in a dataset. Write a 2–3-page narrative summary in a Word document and insert the table and histogram graphic into this document.Note: You are strongly encouraged to complete the assessments in this course in the order they are presented. Descriptive statistics play an important role in analyzing data. It numerically summarizes key characteristics of variables. Measures of central tendency (mean, median, and mode) and dispersion (variance, standard deviation, and range) characterize the probability distribution. A histogram visualizes the distribution of numerical data indicating the number of data points that lie within a range of values. For this assessment, you will perform descriptive statistics and create a histogram for selected variables in a dataset.By successfully completing this assessment, you will demonstrate your proficiency in the following course competencies and assessment criteria:

Perform hypothesis testing on the differences between two groups and create an Excel document. Write a 2–3-page analysis of the results in a Word document and insert the results into this document.Note: You are strongly encouraged to complete the assessments in this course in the order they are presented. Hypothesis testing is a foundational statistical technique used to make decisions about a hypothesis. A hypothesis test compares two mutually exclusive statements (null hypothesis, alternative hypothesis) where only one is true. Hypothesis testing can determine statistical significance by examining the probability that a given result would occur under the null hypothesis. For this assessment, you will perform hypothesis testing on the differences between two groups.By successfully completing this assessment, you will demonstrate your proficiency in the following course competencies and assessment criteria:***Please complete Descriptive Statistics and Data Visualization first.Also, please complete the excel also.

For ANOVA, sum of squares for regression, residual, and total is unknown. df for regression is unknown (X), df for residual is unknown (Y), and df for total is 79. Significance level is 0.05. The following is Coefficients. (Constant) for unstandardised coefficients is 10.02, recovery time for unstandardised coefficients is 1.15, reaction time for unstandardised coefficients is 1.27. The standard error and t-statistic test for (constant), recovery time, and reaction time is unknown. Significance level for (constant) is 0.004, recovery time is 0.003 and reaction time is 0.013. Calculate the sample size and the value of X and Y. Show clear workings. Based on your understanding of F-statistics, does not this model suggests that time taken has a strong relationship with the variables? Explain. What is the linear relationship equation and explain why there is no need to rerun the model at 5% significance level.Very urgent question. Please help.

QUESTION 1Which of the following is an example of chance

Question QUESTION 1Which of the following is an example of chance error?a. Recruiting 200 volunteers for your study, when you need 250b. The researchers use the wrong design for their studyc. The researcher states 2 groups are different when they are notd. It is not related to the design of the studyQUESTION 2Which of the following is needed for a sample size calculation?a. What variable you will measureb. Desired potential for a Type 1 errorc. Knowing if it will be a random sampled. The size of the population from which you will collect your random sampleQUESTION 3a. Which of the following could increase the risk of chance error?b. Using a cross-sectional design with a national survey.c. Using a very small sample size.d. Letting the participants know the research questions, before the study begins.e. Nothing can reduce the risk of chance error that is why it is chance.QUESTION 4Which of the following is the correct definition of Power?a. It is the likelihood that an investigator fails to rejects a null hypothesis that is false and should have been rejected.b. It is the likelihood that an investigator fails to reject a null hypothesis that is true and should have been rejected.c. It is the likelihood that an investigator rejects a null hypothesis that is true and should have been rejected.d. It is the likelihood that an investigator rejects a null hypothesis that is true and should not have been rejected.QUESTION 5Which of the following is a true statement about chance error?a.It can be controlled for in the design stage of the researchb. It cannot be controlledc. It is a form of systematic errord. It can be controlled if the researcher does not collect the data.QUESTION 6Which of the following is true about sample size? a.The sample size you calculate will always be sufficient to conduct your statistical testsb. Unexpected problems collecting data such as questions left unanswered in questionnaires no complete study that can reduce the available sample size.c. The size of the effect you are trying to observe, whether a difference in means or an association between variables is not important when computing sample sized. A sample size of 30 or greater is always sufficientQUESTION 7Which of the following is true about Power? a.A study conducted with insufficient Power has a high chance of a type 1 error.b.

FunTex Garment Trading Ltd. (FTGT) is a garment manufacturing company

Question FunTex Garment Trading Ltd. (FTGT) is a garment manufacturing company headquartered in Hong Kong. Its manufacturing facilities are spread all over Asia, in countries such as China, Malaysia, Thailand, the Philippines, and Vietnam. It produces over 30 million garments, mostly ladies’ apparel, annually. The garment industry is one of the most labour-intensive industries. A number of human factors, such as workmanship and human errors, can easily affect product quality. To assure the quality of products, FTGT provides training for operators to enhance their job skills in different operations such as fabric spreading, cutting, sewing, and finishing. It also tracks operators’ performance, which is used to determine salary increment, bonuses and promotions. Currently, FTGT does not have a systematic approach in reviewing the effectiveness of the training programme. In addition, it is found that the number of product quality issues is increasing, causing a large amount of product rework cost. FTGT would like to use data mining to examine factors associated with good operator performance so that its training resources can be more effectively allocated for quality improvement. TWith reference to the pre-modelling, modelling, and post-modelling stages of data mining, explain the key tasks to be performed when FTGT applies data mining to achieve its business objective.
