To compare biomass of a fish species in two lakes, A and B, a researcher records live- weights of 30 individuals from each lake. She assumes that these two datasets are normally distributed and have equal variance. She calculates Q= (x_A-x_B )/s where x_A and x_B are mean values from the respective lakes, and s is the pooled standard error. What is this quantity Q? (A) Correlation coefficient (B) Regression coefficient (C) t-statistic (D) χ2 -statistic
