A student studying squirrel foraging behaviour believes that "city" squirrels do not travel as far from their nests as "country" squirrels. 6 squirrels in each environment were fitted with radio collars and monitored for a week; total distance travelled from the nest was recorded for each squirrel. The data for the urban squirrels and rural squirrels were compared to test Ho that there is no difference in travel from the nests. What is the appropriate statistical test?

One sample t-test

Dependent samples t-test

Two independent samples t-test

ANOVA

Pearson's product moment correlation

Least squares regression

Contingency table (Independence)

Contingency table (Homogeneity)
