Somebody , one quick problem (25 points):
for making a scatter plot of the data set, which would be the best scale and interval for the axis that represents the amount of fluoride?
water (l) 2 1 1.5 4 3 1 5
fluoride (mg) 1.1 0.8 1.2 3.2 1.6 0.2 3.6

1 to 4 with intervals of 1
2 to 5 with intervals of 0.5
0 to 4 with intervals of 2
0 to 4 with intervals of 0.2
