In a poll conducted by the General Social Survey, 81% of respondents said that their jobs were sometimes or always stressful. Suppose a sample of 500 adults is takes and the proportion that say their jobs were sometimes or always stressful is recorded. Using the values for the mean and standard deviation you selected above, what is the probability that more than 82% of the 500 respondents say their jobs were sometimes or always stressful

Option (C) is correct.

Step-by-step explanation:

A function f : A -> B means every element of A is mapped to a unique element of B, where A and B are non-empty sets.

Now, to check whether a graph is a function or not, there is a test called 'Vertical Line Test'.

In the test, we draw a vertical line passing through the graph. Then:

1. If the line cuts exactly at one point of the graph, then the given graph is a function.

2. If the graph cuts at more than one points, then the graph is not a function as it does not satisfy the definition a function.

Now, in the given graph, if you draw a vertical line on the right side of origin, it will cut at more than one point.

Hence, the graph fails the vertical line test and it is not a function.

So, option (C) is correct.
