Bighof 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: 62°F Cloudy X y y = b= ŷ = 22 Ex= 15; Ey = 84.1; Ex2 = 55; Ey2 = 1,452.93; Exy = 268.8 (a) Find x, y, b, and the equation of the least-squares line.

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
