Question
Looking at the graph on the RIGHT (completely ignore the left one) and want to answer these questions i typed up below. This graph is takken from a report where measurenemnts of the cross section of the production of Z particle in association with charm quark jets. I would like to be able to identify what kind of graph, understand what is depicted by the error bars and then go on to calculayte my own error bars to compare with the approximate bars on the graph
