Expert Solution
for doing the scatterplot i am using minitab. steps for doing scatterplot:-
copy the data in two column of minitab worksheet and name them
"x" and "y" 
GRAPH
SCATTERPLOT
double click
in SIMPLE "IN Y
VARIABLES" select y and " IN X VARIABLES" select x OK.
our scatterplot is:-

You are given a sample of several compounds to separate by paper
chromatography. You draw a pencil line exactly 1.0 cm from the
bottom of the paper, and place a spot of sample on it. You dry the
sample, then develop it in a solvent.
When the chromatogram is taken out of the solvent, the paper is
wet up to 9.0 cm from the bottom of the sheet. The compound you are
interested in shows up as a spot 7.3...
