Without the actual numeric data coordinates, it is impossible to compute the true r value. Though we can estimate. The data points are negatively correlated in a fairly strong manner. We can draw a straight line close to all of these points, so the r value is going to be fairly close to -1. The closer r is to -1, the stronger the negative correlation. Having r = -1 exactly means all of the points fall on some single straight line that slopes downward.
Choice B is the next best choice, but its correlation isn't as strong. So that's why I ruled it out. Choices C and D are ruled out immediately since they are positive values.

If the graph of the second equation in the system passes through (-12, 20) and (4,12), which statement is true?
Answer:
80% confidence interval for the average age of people who attend U of O football games is [42.795 , 44.604].
Step-by-step explanation:
We are given that a sample of 100 attendees and find the average age to be 43.7 years old with a standard deviation of 7 years.
So, the pivotal quantity for 80% confidence interval for the population average start up cost is given by;
P.Q. = ~
where, = sample average age = 43.7 years old
= sample standard deviation = 7 years
n = sample of attendees = 100
= population average age of people
So, 80% confidence interval for the average age of people, is ;
P(-1.2915 < < 1.2915) = 0.80
P(-1.2915 < < 1.2915) = 0.80
P( < < ) = 0.80
P( < < ) = 0.80
80% confidence interval for = [ , ]
= [ , ]
= [42.795 , 44.604]
Therefore, 80% confidence interval for the population average age of people who attend U of O football games is [42.795 , 44.604].
