A study comparing mercury levels in bass fish at one site in the San Francisco Bay is being planned. A t-test using a significance level = 0.05 will be used and power of 80% achieved to detect a difference in mean mercury levels of 0.1mg/g. The required sample size is n= 6. What would happen to the required sample size in each of the following circumstances? The target detectable difference was decreased from 0.1 to 0.05mg/g. The required sample size would: Group of answer choices Stay the same Increase Decrease Not enough information
