For a math assignment, I am required to find the range of data values that would include 95% of my data.
My data is the wait time for a specific bus. I have gathered 20 pieces of data for this, where each number represents how late(+)/early(-)/on time(0) the bus is.
This is the organized data in ascending order:
0, 1, -4, 0, -3, 0, -4, -2, 0, 1, -1, 2, 0, -4, 5, -2, 0, 3, -3, 0.
The link attached down below is my normal distribution graph where I have listed the mean (-0.55), standard deviation(2.4), and the graph information.
What I think the range would be is (-5) - 4. I came to this conclusion by looking at the normal distribution graph above. Although I`m concerned about my answer.
