HELP Calculate the correlation coefficient for the following data, showing all work. What does it tell you about the data?

I will show the way.

Step-by-step explanation:

r is the correlation coefficient

To find SSxy

SSxy= ∑- ∑

To find SSxx

SSxy= ∑- ∑x/n

To find SSyy

SSxy= ∑- ∑y/n

if your r is near +1, it shows strong positive correlation. Y is proportional to X.

And if it nears -1, it would show strong negative correlation. Y is inversely proportional to X.

can you rephrase the question ? it is unclear : -)

step-by-step explanation:

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
