Expert Solution
Step 1
Given that information
Suppose that Bighorn sheep are beautiful wild animals found throughout the western United States. Let X be the age of a bighorn sheep (in years), and let Y be the mortality rate (percent that die) for this age group.
For example, x = 1, y = 14 means that 14% of the bighorn sheep between 1 and 2 years old died. A random sample of Arizona bighorn sheep gave the following information:
x 1 2 3 4 5
y 13.0 17.1 14.4 19.6 20.0
n = 5, Σx = 15; Σy = 84.1;
Σx^2 = 55; Σy^2 = 1,452.93; Σxy = 268.8
