Look at the scenario that is presented in the attached document and select an appropriate experimental design.

Position (Pj)	Depth from Top of Pool
0 ft	5 ft	10 ft
1	4.90	4.90	4.94
4.91	4.89	4.80
2	4.90	4.89	4.75
4.91	4.89	4.83
3	4.94	4.91	4.86
4.90	4.91	4.83
4	4.93	4.94	4.83
4.91	4.90	4.89
5	4.90	4.94	4.83
4.87	4.90	4.86

You want to determine the effect of both depth and position in a pool on the concentration of chlorine in parts per million. Concentrations are measured at three depths from the surface of the pool (0 ft, 5 ft, and 10 ft). At each depth, measurements are taken at five different lateral positions in the pool.
