<span>This difference is explained by the concept of statistical error. Statistical error simply means the difference between the 'true value' of some statistic (like the population mean) and the estimated value of some sample statistic (like a sample mean). Since no sample perfectly represents any population, there is always some statistical error involved when trying to use sample means to predict population means.</span>

The table and the graph each show a different relationship between the same two variables, x and y:
SCORPION-xisa [38]
When x=2 y = 110 which means when when x=1 y = 55
the graph would be 11*55 or 605
The table would be 280/4= 70 70*11=770 
Which means the difference is 770-605=165

165 is ur answer
