The best scale and interval to adopt for the amount of Fluoride axis would be 0 to 8 with intervals of 0.2
To make a decision on the scale and interval to adopt when making a graph ;
- We need to examine the the range of the values in the distribution.
- Data for the amount of Fluoride ranges from 0.4 to 7.1
- The number of values in the distribution is 7.
- Lower scale value must be below the minimum Fluoride value preferably 0
- Maximum scale value must be above the maximum Fluoride value.
- Hence an interval of 0 to 8 would suit the axis.
- The interval is the value of each unit represented on the graph.
- A scale of 4 would be too large to depict all the 7 values with an interval of 8 units
- Hence, the most reasonable scale from the option would be 0.2 as it would allow the points to be properly spaced on the graph.

I think letter B is the answer
Explanation:
I provided this for who may ask later
Answer:
The population of the colonies that later became the United States increased steadily in the decades prior to , and including, the American revolution. The first decennial census took place in 1790 . Since that time, the natural increase, i.e, the excess of births over deaths, has been a constant contributor to popular growth. The other factor, immigration, has ranged for negligible to large at various points in the nation's history.
After 1830, immigration began to grow again. Although the birth rate showed a decline , the net population growth rate remained high until after the Civil War. In the decade ending 1870, population growth dropped below 30% for the first time in the nation's history. Substantial immigration kept the population rising at 20% or more for each decade until 1920, when the effect of Word War I reduced it to 14.9% .
