STATISTICS

1. 1Ventilation rates in sh can be measured as opercular mmrements per minute (the op- erculum is a bony plate that covers the sh's gill]. In order to study how Ventilation rates change with temperature, ve temperature levels from H] to 13 "C are chosen. The researchers might be able to obtain 35 sh1 but there is also a chance that they will only have 'i" sh available for the experiment. The sh will be placed in water tanks in which the temperature will be manipulated. There are only 7 water tanks. Propose a design for each of the two situations: a A: 35 sh n B: Tsh Be sure to specify experimental unit, blocking and treatment factors1 design and random- ization. Make a sketch if this helps with illustrating what you mean. [9]
