I'm given a cumulative probability graph, however i can't post any images. Thus, the X and Y coordinates of the graph are:
X:
2.5 7.5 12.5 17.5 22.5 27.5 32.5 37.5 42.5 47.5 52.5 57.5
Y:
0 0 0 0.07 0.17 0.27 0.37 0.47 0.57 0.67 0.77 0.87
How do i calculate the mean and variance of this cumulative probability graph?
Thanks alot!!!!
EDIT:
Now that i have enough rep points, i can post the picture of the graph.
Given D = 0.07
