Textbook Question
Chapter 9, Problem 2EA
In a Latin square, each treatment condition occurs first one time, second one time, third one time, and so on. Ideally, every possible sequence of two treatments should also occur exactly one time. For example, if two treatments are identified as A and B, then the sequence AB and the sequence BA should each occur one time in the square.
- Try to construct an ideal Latin square for an experiment with four treatment conditions identified as A, B, C, and D. This may take a little time, but it can be done.

- Wind Mountain is an archaeological study area located in southwestern New Mexico. Potsherds are broken pieces of prehistoric Native American clay vessels.

Each year many small plots of equal size but different soil/fertilizer conditions are planted with wheat. At the end of the growing season, the yield (in pounds) of the wheat on the plot is measured. Suppose for a random sample of years, one plot gave the following annual wheat production (in pounds): 4.46 4.21 4.40 4.81 2.81 2.90 4.93 3.54 4.16 4.48 3.26 4.74 4.97 4.02 4.91 2.59 Use a calculator to verify that the sample variance for this plot is .

It is hypothesized that archaeological sites tend to lose their cultural identity and specific cultural affiliation as the elevation of the site increases. Let x be the elevation (in thousands of feet) for an archaeological site in the southwestern United States. Let y be the percentage of unidentified artifacts (no specific cultural affiliation) at a given elevation. Suppose that the following data were obtained for a collection of archaeological sites in New Mexico: x 5.50 6.00 6.75 7.00 7.75 y 37 38 92 70 99 Find the equation of the least squares line .
