Question

What can the reader conclude from the graph?
A. A company selling telephones most likely has only a 40% chance of surviving for at least four years.
B. A company offering physical therapy most likely has only an 80% chance of surviving for at least two years.
C. A company offering cleaning services most likely has only a 50% chance of surviving for at least seven years.
D. A companies selling diabetes supplies has only a 60% chance of surviving for at least three years.

Answer 1

The second alternative is correct (B).

This is a question of graphic interpretation. The question is about the survival rate of companies for two industrial sectors: health care (yellow line) and the rest of the other industries (green line).

The interpretation is very simple. Just look at the axis of the orders (vertical) the percentage of survival of the industry and the axis of the abscissa (horizontal) the amount of years that the industries last.

Physiotherapy companies are part of the service industry, so we should look at the yellow line. It can be observed that over the course of two years the yellow line is still above 80%, as stated in question B.

In other words, a physiotherapy company has an 80% probability of being in operation after two years of activity.

Answer 2

The readers could conclude that a company offering physical therapy most likely has only an 80% chance of surviving for at least two years.

Interpretation of graph

The graph illustrates that there are two companies that are health care, which is shown through the yellow line, and other sectors, which is shown by the green line.

Therefore, by seeing the yellow line it could be said that over two years health care service offers the probability of surviving around 80 percent that is more than other industries, which is falling from passing years.
