Scenario: You are conducting a study on the influence of population density on body mass in leafy seadragons in oceans off the coast of Australia. You are investigating the biological hypothesis that population density influences body length, and the prediction that individual leafy seadragons in higher density populations will have smaller body length. You have randomly sampled 15 leafy seadragon individuals from each of two locations in Australia, one location has a naturally low population density and the other area has a naturally high population density. The descriptive statistics of leafy seadragon body length (in cm) are shown in the table. What value best represents the t-statistic? (only 2 decimal places are given, recall there could be very minor variation due to rounding.) Low population density High population density X̄ 16.3 15.3 s 2.1 1.7 n 15 15
