Question

find a linear regression line basicaly to find the least squares best fit in the form Temp = A + B*time. (asked me the data file) and I did in R software

Time Temp (°C) 0:00 -0.6 1:00 -0.5 2:00 0 3:00 0 4:00 0 5:00 -0.4 6:00 -0.3 7:00 -1.1 8:00 -0.5 9:00 1.4 10:00 2 11:00 3.5 12:00 2 13:00 1.9 14:00 2.1 15:00 2 16:00 1.6 17:00 1 18:00 0.4 19:00 -0.4
