Researchers were interested in the relationship between farmers’ approach to their cows and the cows’ milk yield. After surveying a random sample of 120 farmers, the researchers found that on farms where cows were called by name, milk yield was 258 liters higher on average than on farms where this was not the case.

Can we conclude that calling the cows by name caused the cows to produce more milk? Why?

a)

Yes, because the sample size was large

b)

Yes, because the farmers were randomly selected

c)

Not necessarily, because the sample size was too small

d)

Not necessarily, because this wasn't an experiment

To check the effect of hot temperatures on the elasticity of two brands of rubber bands, one box of Brand A and one box of Brand B rubber bands are tested. Ten bands from the Brand A box are placed in a warm car in the sun for two hours and ten bands from the Brand B box are kept at room temperature. The amount of stretch before the breakage is measured on each rubber band, and the mean for the hot bands is compared to the mean for the others. Is this a good experimental design?

a)

No, because the means are not proper statistics for comparison.

b)

No, because more than two brands should be used.

c)

No, because more temperatures should be used.

d)

No, because temperature is confounded with brand.

e)

Yes
