(1 point) 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 c 2 2 3 6 5 8 Days y 6 21 35 43 41 45 Use a calculator or software to find the following values. (a) Find the mean and standard deviation of c. MEAN: 4.3 STANDARD DEVIATION: (b) Find the mean and standard deviation of y. MEAN: STANDARD DEVIATION: (c) Find the correlation r between a and y
