the slope of the true least-squares regression line AND the mean value of y? Given that y = 0.449x - 30.27, x = 95 degrees (for the 2nd question), and the data below are the temperatures on randomly chosen days during a summer class and the number of absences on those days:
(temperature x, # of absences y): (72, 3), (85, 7), (91, 10), (90, 10), (88, 8), (98, 15), (75, 4), (100, 15), (80, 5). I'd like the answers...not just the method. Thanks!
