To check this is entered correctly on your calculator, press [stat], go to CALC, and select "2:2-Var Stats". Run this on your two lists. When you scroll down the list, you should see Exy=56240 Enter the data into your calculator and obtain a linear equation of best fit using the linear regression feature. Type the equation here, in the form y = mx + b. If necessary, round the values of m and b to three decimal places. Based on your regression equation, what score would you predict for a student who has studied for 1 hour and 40 minutes? Round your answer to a whole number of points. points Based on your regression equation, how much time should a "typical" student spend studying if they wanted to score at least 80 points on the exam? Round your answer up to the next full minute. minutes
