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
Sphinxa [80]

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.

How can you test a water source to see whether it is acidic or not
podryga [215]

Answer:

The easiest way to test if water is acidic is to use litmus paper. Litmus paper is a paper that contains special dyes that will change color when exposed to acids or bases. In your case, if you dip blue litmus paper into water samples and it turns pink or red, then the water is acidic.
