4.28 Ebola and Gorillas. The deadly Ebola virus is a threat to both people and gorillas in Central Africa. An outbreak in 2002 and 2003 killed 91 of the 95 gorillas in seven 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 time in number of days until deaths began in each later group:¹7 L EBOLA Distance Time 1 4 3 21 4 33 4 41 4 43 5 46 a. Make a scatterplot. Which is the explanatory variable? What kind of pattern does your plot show? b. Find the correlation r between distance and time. c. If time in days were replaced by time in number of weeks until death began in each later group (fractions allowed so that four days becomes 4/7 week), would the correlation between distance and time change? Explain your answer.
