1. The above data was collected to see if hours spent gaming affects the amount of sleep a person gets. (a) (1 point) What is the response variable? (b) (1 point) What is the explanatory variable? (c) (1 point) What could be a possible lurking variable? (d) (3 points) What is the correlation between both variables? (e) (5 points) Find the equation of the linear regression line. (f) (3 points) Graph a scatterplot and add your best fit line. (g) (2 points) Your friend spends 3 hours gaming, what is their predicted amount of sleep? Gaming (Hours) Sleep (Hours) 10 4 3 8 5 12 1 7 0 9 2. (5 points) A researcher took a sample of 50 high school students who work and found that their mean SAT score was 1020. Generally, high school students have an SAT mean of 1100 and a standard deviation of 210. Complete significance testing and state your conclusion. 3.
