Normal Probability Plot for x 90 70 100 100 Data 200 300

Explanation / Answer

Since, the trend of the normal probability plot is approximately linear i.e. at an approximate angle of 45 degrees with the x-axis, we can conclude that probability plots indicate that the sample data could have come from a population that is normally distributed
