Smoking is a risk factor affecting patient’s cardiovascular system (and not only cardiovascular system, of course). Jennifer was asked to take random samples of male Healthy Life members recently admitted to hospitals in GTA with heart attacks. She compiled two large separate files consisting of those male residents of Toronto who smoked and those who never smoked. The purpose of this research is to prove that the first heart attack occurs at an earlier age if a patient smoked. After carefully analyzing the data Jennifer came up with the hypothesis that male smokers who suffer a first heart attack are, on average, seven years younger than non-smoking males who suffer a first heart attack. If you know that the population variances are equal, what function is most appropriate: Data Analysis t-Test: Two-Sample Assuming Equal Variances or Data Analysis t-Test: Two-Sample Assuming Unequal Variances. Please help Jennifer Nguyen to conduct the test at 1% significance le
