Question: BP oil leak.In the summer of 2010, an explosion on the Deepwater Horizon oil drilling rig caused a leak in one of British Petroleum (BP) Oil Company's wells in the Gulf of Mexico. Crude oil rushed unabated for 3 straight months into the Gulf until BP could fix the leak. During the disaster, BP used suction tubes to capture some of the gushing oil. In May of 2011, in an effort to demonstrate the daily improvement in the process, a BP representative presented a graphic on the daily number of 42-gallon barrels (bbl) of oil collected by the suctioning process. A graphic similar to the one used by BP is shown below.

a.Note that the vertical axis represents the "cumulative" number of daily barrels collected. This is calculated by adding the amounts of the previous day's oil collection to the current day's oil collection. Explain why this graph is misleading.

b.Estimates of the actual number of barrels of oil collected per day for each of the 8 days are listed in the accompanying table. Construct a graph for these data that accurately depicts BP's progress in its daily collection of oil. What conclusions can you draw from the graph?

Step by step solution

01

Given information 

There are 3 straight months in the Gulf until BP could fix the leak. Bp presented a graphic on the daily number of 42 galloon barrels(bbl) of oil collected by the suctioning process.

02

(a) Explaining misleading of graph

The misleading graph is because they do not take in a range. So, there are misleading of graphs in the range. The graph's vertical axis depicts the total amount of barrels gathered every day, which is calculated by adding the quantities gathered the preceding day to the current day's oil gathering. This graph is deceiving since the quantity of days increases, so does the number of barrels gathered daily. In accordance with the query, the bar in the graph reflects the total amount of barrels gathered; this is not a true picture of daily oil collecting

03

(b) Estimates the actual number of barrels per day and draw the graph to write the correct conclusions 

From these graphs, we conclude that comparison number of barrels. The vertical axis in the graph depicts the actual number of barrels gathered daily. This graph is a true portrayal of BP's daily oil gathering. The graph reveals that the 18th of May was the busiest day for BP during the week. And the 16th of May was the day on which BP gathered the least over the week.
