Answer:

1. Most people without iphones have MP3 Players (first correlation), meaning that if you have an iphone you most likely don't NEED a MP3 player (this may not be a fact just a thought). Also having a iphone most of been pretty common during this time, cause only 12 out of 50 people didn't have one.

2. I gathered the percents of how many people with iphones and a MP3 player, and how many without iphones have a MP3 player. About 53% of people with iphones have a MP3 player while a whopping 67% of people without iphones had a MP3 player. This helped with the correlation and can also help the gathering of data be more useful to other questions. For example, "What percentage of people have an iphone?".

Answer: $\displaystyle \boldsymbol{-\frac{1}{2}}$

================================================

Work Shown:

$\displaystyle L = \lim_{\text{x}\to 1^{+}} \frac{1-\text{x}}{\text{x}^2-1}\\\\\\\displaystyle L = \lim_{\text{x}\to 1^{+}} \frac{-(\text{x}-1)}{(\text{x}-1)(\text{x}+1)}\\\\\\\displaystyle L = \lim_{\text{x}\to 1^{+}} \frac{-1}{\text{x}+1}\\\\\\\displaystyle L = \frac{-1}{1+1}\\\\\\\displaystyle L = -\frac{1}{2}\\\\\\$
