Natalie performs a chemistry experiment where she records the tenperture of an ongoing reaction.The solution is 93.5 C after 3 minutes;90 C after 5 minutes,84.8 C after 9 minutes; 70.2 C after 18 minute; 54.4 C after 30 minutes;42.5 C after 37 minutes; and 24.9 C after 48 minutes.Perform a linear regression on this data to complete the following items.
What does the value of the correlation coefficient tell you about correlation of the data?

Enter these data points into some graphing software, and ask the computer to perform a linear regression on the data (find the best-fit line that goes through the data points) The computer should also be able to calculate the correlation coefficient. If the correlation coefficient is 1, all the data points will lie along this line; The farther the correlation coefficient is from 1 and closer to 0 indicates that the points will be more scattered with respect to this line
