In the U. S., from 2004-2015, the correlation coefficient for the relationship between the size of a cell phone data plan, x, and the number of text messages sent, y, is r =0.97. Describe what this means about the relationship between the data plan size and the number of text messages sent in the U. S.
Answer options:
- There is no correlation between the size of the data plan and the number of text messages in the US.
- There is a weak positive linear correlation between the size of a cell phone data plan and the number of text messages sent.
- There is a strong negative linear correlation between the size of a cell phone data plan and the number of text messages sent.
- There is a strong positive linear correlation between the size of a cell phone data plan and the number of text messages sent.
I'd appreciate if you included an explanation, but an answer is fine.

Data from 2005 for various age groups show that for each $100 increase in the median weekly income for whites, the median weekly income of blacks increases by $105. also, for workers of ages 25 to 54 the median weekly income for whites was $676 and for blacks was $527. (a) let w represent the median weekly income for whites and b the median weekly income for blacks, and write the equation of the line that gives b as a linear function of w. b = (b) when the median weekly income for whites is $760, what does the equation in (a) predict for the median weekly income for blacks?
