Plot a graph of y-axis against x-axis.
The graph should be a straight line passing through:
(-2,0.8) , (-1,-0.4) , (0,0) , (1,0.4) and (2,0.8)
1x25=25
5x5=25
1x20=20
2x10=20
4x5=20
x^5 is the biggest you can take out of x^5 and x^6 and 5 is the biggest number you can take out of 20 and 25
5m^5

Otherwise, the z-distribution(z-table) is used.
So the answer to this question is the t-distribution.
