This dataset contains consumer responses indicating the number
of times they had to send their product for repair and their
satisfaction with the repair process. Create a graph which can be
used to visually demonstrate the relationship between the two
columns of data. Ensure that the chart is professional with
appropriate titles, axis labels, etc. Note any observations you see
in your visualization (type these as sentences directly into an
Excel cell(s)).

The accompanying table lists the ages of acting award winners
matched by the years in which the awards were won. Construct a
scatterplot, find the value of the linear correlation coefficient
r, and find the P-value of r. Determine whether there is
sufficient evidence to support a claim of linear correlation
between the two variables. Should we expect that there would be a
correlation? Use a significance level of
alphaαequals=0.050.05.
