A study of ants in a certain country returned data on annual rainfall, maximum daily temperature, and number of ant species in 11 study sites. The data from the study was used to estimate the straight-line model relating annual rainfall in millimeters (y) to maximum daily temperature (x).

Give the values of SSE, s, and s, shown on the technology printout. SSE =O (Type an integer or a decimal.) (Type an integer or decimal rounded to four decimai piaces as needed.) (Type an integer or decimal rounded to four decimal places as needed.) b. Give a practical interpretation of the value of s. Choose the correct answer below. (Round to the nearest whole number as needed.) A. The prediction error for the average annual rainfall is B. Most (about 95%) of the errors of prediction will fall within C.
