1. The problem statement, all variables and given/known data Hello everyone! I have been trying to figure out what i should do to show correlations in my biology report about smoking and heart rate. I have conducted 41 trials with people who are -Non smokers and exercise -Smokers and exercise -No exercise smokers -Smokers and no exercise I have means, and standard deviations. What statistical test should i do to show that each group is different? should i use a student's t-test? 2. Relevant equations T-test Chi square? 3. The attempt at a solution I think that t-test i good as i can compare the values and determine wheter they are due to chance or not. However i dont really know Thanks!
