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:x12345y15.220.914.419.620.0Σx = 15; Σy = 90.1; Σx2 = 55; Σy2 = 1659.37; Σxy = 278.60
