[Q7: Only answer if you ABSOLUTELY know how to solve AND the answers match up ((tired of getting wrong replies.) So, please make sure you’re really certain. [It’s appreciated.])

Really Explain EACH STEP, including any formulas you used (& how to use the formula), and explain how to compute with a TI-84 preferably/when possible.]

NO JUST POSTING THE ANSWER WITH NO EXPLANATION/ NO CONVINCING EXPLANATION, I WILL ASSUME IT'S WRONG, AS HAS BEEN THE CASE BEFORE. IF YOU'RE THIS TYPE, MOVE ON.

Explanation / Answer

The second graph clearly shows that there is a high negative correlation.

As the x values increase, the y values are decreasing. Hence the pearson coefficient in this case should be -.804

The second graph is not showing much of proper correlation. But little positive correlation exists.

Thus the possible answer for this is .329
