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

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
