Question 1) in a random sample of 10 on-line statistics students, information was collected about their minutes studied and their chapter test scores. x is the minutes studied, and y is the test score.
x : {20,30,45,60,80,90,45,120,90,70} y: {50,45,55,70,80,90,80,100,95,85}
is this relationship positive, negative or no relation?(positive)

using the data from question #1, what is the equation of the line of best fit? (for future reference: line of best fit, linear regression equation, and least-squares line are all the same thing y=ax+b). round your answers to the nearest tenth. x : {20,30,45,60,80,90,45,120,90,70} y: {50,45,55,70,80,90,80,100,95,85}
