I can't figure out what I am doing wrong. Attaching my work.. would love some guidance or step-by-step to show how to solve this correctly. I'm sending one more page. Thanks for your help!

An outbreak of the deadly Ebola virus in 2002 and 2003 killed 91 of the 95 gorillas in 7 home ranges in the Congo. To study the spread of the virus, measure distance by the number of home ranges separating a group of gorillas from the first group infected. Here are data on distance and number of days until deaths began in each later group:

Distance ?	4	5	3	5	6	8
Days ?	6	17	32	37	48	48

Find the correlation ? between ? and ?. (As always, if you round, make sure you do so correctly, only round your final answer, and keep at least three decimal places.)

Expert Solution

Step 1

We have given information, about an outbreak of the deadly Ebola virus in 2002 and 2003 that killed 91 of the 95 gorillas in 7 home ranges in the Congo.

The spread of the virus is measured distance by the number of home ranges separating a group of gorillas from the first group infected. The data of distance and the number of days until deaths began in each later group is given as follows:
