question 123

Essay

The table below lists weights (carats) and prices (dollars) for randomly selected diamonds. Is there sufficient
evidence to suggest that there is a linear correlation between weights and prices? Construct a scatterplot, and
find the value of the linear correlation coefficient r.
Also find the P-value or the critical values of r using $\alpha = 0.05$ $$\begin{array} { | l | l | l | l | l | l | l | } \hline \text { Weight } & 0.3 & 0.4 & 0.5 & 0.5 & 1.0 & 0.7 \\\hline \text { Price } & 510 & 1151 & 1343 & 1410 & 5669 & 2277 \\\hline\end{array}$$
