The following regression model investigates the determinants of years of schooling.educ = Bo + B₁ * motheduc + B₂ fatheduc + ß* income +84 * ability + uwhere motheduc is mother's education, fatheduc is father's education, sibs is number of siblings, and ability is a person's ability.Write the reparameterized model and explain how you would use it to test the hypothesis that mother's education and father's education have the same effect on years of schooling.

A study of king penguins looked for a relationship between how deep the penguins dive to seek food and how long they stay underwater. For all but the shallowest dives, there is a linear relationship that is different for different penguins. The study report gives a scatterplot for one penguin titled " The relation of dive duration (DD) to depth (D)." Duration DD is measured in minutes and depth D is in meters. The report then says, " The regression equation for this bird is: DD = 2.02 + 0.0081 D. (a) What is the slope of the regression line?. ANSWER minutes per meter. (b) According to the regression line, how long does a typical dive to a depth of 400 meters last? ANSWER minutes. Speak

The least-squares regression equation is y=784.6x+12,431 where y is the median income and x is the percentage of 25 years and older with at least a bachelor's degree in the region. The scatter diagram indicates a linear relation between the two variables with a correlation coefficient of 0.7962. In a particular region, 26.5 percent of adults 25 years and older have at least a bachelor's degree. The median income in this region is $29,889. Is this income higher or lower than what you would expect? Why?
A new footwear manufacturer is trying to compete with the major brands by investing heavily in Research and Development (R&D). Their goal is to produce a premium lifestyle sneaker that is more comfortable, longer lasting and more stylish than any of their competitors. Below are some data on dollars spent on R&D and new customers acquired for the last 5 quarters. Regression Equation: Y= 0.5 + 1.35X New Customers R&D Dollars Acquired (in millions) (in thousands) 8 12 12 15 13 18 14 20 18 25 Based on looking at the numbers and/or sketching a scatter-plot, what conclusion can we draw about the data? The variables are negatively correlated You cannot tell until we perform some calculations There does not appear to be a strong correlation between the variables The variables are positively correlated
The outcome variable is degree of brand liking (measured essentially as some sort of percentage). Higher numbers mean it was “liked” more. There are two potential predictors. The first is moisture content which is controlled at levels of 4, 6, 8, and 10. The second is sweetness, the recorded values are 2 and 4. (Matrix plot is attached) Comment on what you expect the regression analysis to show with regard to the relationship of the two predictors with the response. Comment on the scatterplot that shows the predictors against each other. Note that each “point” on this graph in fact represents 2 data points. What does this imply about the “experimental design”? About “collinearity”? About the ways in which we will be able to discuss the effects of moisture and sweetness?
