The following pairs of observations tell the result of the laboratory experiment y and the temperature x at which the laboratory experiment was carried out. Observations as following: i xi yi i xi yi 1 100 45 7 150 69 2 110 51 8 160 74 3 120 54 9 170 78 4 125 53 10 180 86 5 130 59 11 190 89 6 140 63 12 200 94 So the question regarding the table above would be (a) Draw a scatter diagram of the table. (b) Visually draw a line that fits the data (in table) as well as possible. (c) Fit a linear model to the data, i.e. estimate the PNS estimates of the regression line. Compare the regression line you get with the one you drew in (b) (ie compare the slopes/intercepts). (d) Predict the result of the laboratory experiment when the experiment is performed at a temperature of 185. R software or other software for linear regressions should not be used to solve this.
