The latter is the correct answer.The average is exactly 0.5 (where the peak of the graph occurs), so the second option is false.Each line points to the left or to the right of the media that is supposed to indicate a certain number of standard deviations away from the mean. (for example, the line between 0.3 and 0.4 is a standard deviation away from the mean, while the line at 0.2 is two standard deviations away). This means that the standard deviation should be 0.15, as , so that the first choice is also false.0.7 clearly it is between one and two standard deviations from the mean, so the third option is false.
