Homework Help: Should I use a T-test?

  1. Mar 20, 2010 #1
    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
