Discuss Can a person’s executive function (Executive) predict his/her verbal IQ (verbIQ)?
Q3. Checking the normality assumption (6 points total) In this question set, we examine the three scale variables to check the normality assumption. – Use histogram to get a visual evaluation. – Use Shapiro-Wilk’s test of normality to determine if a variable meets the assumption A. Check VerbIQ for the normality assumption. 1. Paste the […]

Case Study: Air Pollution and Respiratory Symptoms Air pollution is a serious problem in many places. One form of air pollution that is suspected to cause respiratory illness is particulate matter (PM), which consists of tiny particles in the air. Particulate matter can come from many sources, most commonly ash from burning wood or from […]
Describe each variable in your two models (don’t forget to describe the dependent variable), and offer a brief hypothesis of how you expect the independent variables will affect average shipping costs. Pay close attention to the specifics of how your variables are measured. Your variable descriptions and hypotheses should include some discussion of the differences between your two models.
1) Your group should specify two different shipping costs models, with each one using a different measure of quantity. The remaining independent variables can remain the same. 2) Describe each variable in your two models (don’t forget to describe the dependent variable), and offer a brief hypothesis of how you expect the independent variables will […]
