Solved in 2 steps
- Explain the kind of changes occur in the coefficient of a non variable while making changes in the orginal model ?what do the standardized regression weights or coefficients tell you about the ability of the predictors to predict the dependent variable?Discuss the five general techniques for controlling extraneous variables.
- Discuss the differences between a causal model and a time-series model. Be sure to provide examples to illustrate your understanding of these concepts.If two variables are highly correlated, does this imply that changes in one cause changes in the other? If not, give at least one example from the real world that illustrates what else could cause a high correlation.A researcher is interested in the relationship between students’ participation in two after school programs and academic achievement. She states the following hypothesis in the description of her study: H1. Children who participate in an after school program that emphasizes critical thinking skills will score higher on measures of academic achievement and self esteem than students who participate in a program that emphasizes rote memorization. What are the variables in this study? What would be good names for the variables? Identify the independent variable(s) and dependent variable(s). Describe how each variable varies and provide justification for why each variable varies the way you describe?
- An advertising executive claims that there is a difference in the mean household income for credit cardholders of Visa Gold and of MasterCard Gold. A random survey of 15 Visa Gold cardholders resulted in a mean household income of $68,420 with a standard deviation of $9100. A random survey of 6 MasterCard Gold cardholders resulted in a mean household income of $59,200 with a standard deviation of $9200. Is there enough evidence to support the executive's claim? Let μ1 be the true mean household income for Visa Gold cardholders and μ2 be the true mean household income for MasterCard Gold cardholders. Use a significance level of α=0.05 for the test. Assume that the population variances are not equal and that the two populations are normally distributed. Step 1 of 4: State the null and alternative hypotheses for the test. Step 2 of 4: Compute the value of the t test statistic. Round your answer to three decimal places. Step 3 of 4: Determine the decision rule for rejecting the…What is the primary difference between a time-series model and an associative model?Quarterly sales of a local department store over a 4-year period are given below: Quarters 2016 Q1 Sales (in millions) 500 Quarters 2018 Q1 Sales (in millions) 560 2016 Q2 490 580 2018 Q2 2018 Q3 2018 Q4 2019 Q1 2019 Q2 2016 Q3 570 630 2016 Q4 2017 Q1 2017 Q2 750 720 480 540 500 590 2017 Q3 580 2019 Q3 620 2017 Q4 740 2019 Q4 790 The data shows sign of seasonality.
