rescarcher wanted to study if family factors had an impact of academic achievement. The family factors investigated were family income, parents' level of education, parents' support and encouragement to their children, and parents' interests in their children education. Answer the Questions 1 to 4 only from the above information: Q.1 Write the objective of research. Q.2 Write any two possible independent variables. Q.3 Write the possible dependent variable. Q.4 Write the relationship between the variables.

Which types of decisions should the decision trees be used to address for?

State whether the following statements are true or false. If the statement is false, write the correct answer:   Qualitative Methods are more accurate, for they involve analyzing numeric data and taking decisions based on previous numbers and statistics.   Answer:   Quantitate data is used in decision making especially for companies and organization that are new in the market.   Answer:

Refer to the research analysis output below.  Which is NOT a reasonable interpretation of this output?   1. The median Growth from treatment to treatment for this research is significantly different. 2. This is a non-parametric research analysis 3. The original data are most likely non-normal 4. There are most likely outliers in the data 5. The research analysis conducted is the Kruskal -Wallis test

Describe how decision analysis is similar to and different from simulation analysis and scenario analysis (at least 75 words)

what is the standardized regression? what do the standardized regression weights or coefficients tell us about the ability of the predictors to predict the dependent variable?

Business decision support systems, sometimes known as DSSs, provide assistance in making choices that require many steps.Describe the many components that make up the DSS. In what ways does DSS modify IT?

1. Discuss the process you would  employ to develop a suitable  balanced scorecard for a tourist site organization and give examples of measures that would be incorporated within it.   2. Discuss how break even analysis can aid management in decision-making.   3. Discuss the practical difficulties associated with the use of breakeven analysis by managers in decision-making.

I want answer with explanation... I'll upvote you... Only typed answer I want...

The decision tree is not correct. You mixed between types and numbers please re-calculate

Hypothesis test has been widely used in health care, pharmacy, lab experiments, finance, manufacturing, service and others.  Option I: Identify a decision process within your work or business interest that have been resolved based on hypothesis test You need discus the following questions: Describe your case briefly (i.e., a decision process within your work or business interest OR a news item) Identify the null and alternative hypotheses in your case Identify the population and the sample, to the extent that you can from the information given. What was the result of their hypothesis test?

Which best describes the null hypothesis associated with an Analysis of Variance (ANOVA)?   Group of answer choices a. Ho:  Variance 1 = Variance 2 = Variance 3 b. Ho:  Standard Deviation 1 = Standard Deviation 2 = Standard Deviation 3 c. Ho:  Proportion 1 = Proportion 2 = Proportion 3 d. Ho:  Median 1 = Median 2 = Median 3 e. Ho:  Mean 1 = Mean 2 = Mean 3

Review the six-step decision-making process outlined below, then answer the question that follows. Step 1: Define the problem Step 2: Identify alternatives to the problem Step 3: Evaluate the identified alternatives Step 4: Make the decision Step 5: Implement the decision Step 6: Evaluate the decision A customer is frequently slow in paying invoices—sometimes as late as 30 days. Is this because (1) he does not manage his books well, (2) he is trying to conserve his working capital as long as possible, or (3) his own customers are often slow in paying him for the goods he sells them? Consider that there may be another explanation as well. Based on your ethical concerns, use the six-step decision-making process to arrive at a solution. Explain your reasoning for each of these steps.

what do the standardized regression weights or coefficients tell you about the ability of the predictors to predict the dependent variable?

. What are the advantages and disadvantages of Regression Model, Econometric Model, Driving Indicator Models?

Paraphrase this one. Analyze and elaborate in 85 words. Regression analysis data also helps you understand whether the relationship between two different variables can give way to potential business opportunities.

3. The marketing group for a cell phone manufacturer plans to conduct a telephone survey to determine consumer attitudes toward a new cell phone that is currently under development. In order to have a sufficient sample size to conduct the analysis, they need to contact at least 100 young males (under age 40), 150 older males (over age 40), 120 young females (under age 40), and 200 older females (over age 40). It costs $1 to make a daytime phone call and $1.50 to make an evening phone call (due to higher labor costs). This cost is incurred whether or not anyone answers the phone. The table below shows the likelihood of a given customer type answering each phone call. Assume the survey is conducted with whoever first answers the phone. Also, because of limited evening staffing, at most one-third of phone calls placed can be evening phone calls. How should the marketing group conduct the telephone survey so as to meet the sample size requirements at the lowest possible cost? Who Answers?…

Explain how decision trees might be used in several of the OM decisions.
