   Question

   Do people who are running at least 10 kilometres per week have a higher heart rate at rest than people who cycle at least 10 kilometres per week? For the survey, the respondents opted for one of both sports. The resting heart rate of 200 runners and 200 cyclists was recorded after several months of exercise.

   To answer the question, should you use proportions OR averages of a dependent OR independent sample?

   
   
   1. FALSE: Two proportions of independent samples.
   2. FALSE: Two proportions of dependent samples.
   3. TRUE: Two averages of independent samples.
   4. FALSE: Two averages of dependent samples.
   
   

   Solution

   Two averages of independent samples. An average of the heart rate of people running at least 10 kilometers a week and an average of heart rate of those who cycle at least 10 kilometers per week. The samples are independent because it are different people.
