HW1 (1):1. We wish to determine the average resting heart rate of 18-year-old males. We measure the heart rate of 30 different 18-year-old males and take the average of the measurements. (Matching)A. The average of the 30 heart rate measurementsPopulation E B. The average heart rate of all members of the populationVariable F C. The heart rates of our 30 chosen individualsParameter B D. All malesSample G E. All 18 year old malesData C F. Heart rateStatistic A G. The 30 males chosen2. What is the difference between a parameter and a statistic?A parameter summarizes the population and a statistic summarizes the data.3. Consider the population below. Since a large portion of the population is obese, this should clearly be considered an obese population. Our parameter of interest is the proportion of the population that is obese. The proportion of obese individuals in our population is .6094 (60.94%).a) If 32% of our data was obese, would our data be misleading or would it be similar to the truth?It is misleading because that is far from the truth. It does however say that there is a problem (just underestimated)b) If 62% of our data was obese, would our data be misleading or would it be similar to the truth?Not misleading.c) If 80% of our data was obese, would our data be misleading or would it be similar to the truth?Misleading – over estimates the problem.4. Suppose that we wish to quantify the overall health of our population. Think of 5 variables that we may wish to measure.Resting heart rate, percent body fat, daily exercise, eating habits, drug habits, illnesses – lots of possibilities5. Suppose that one of your variables was percent body fat. Why is that a variable?Because it varies from person to person6. Suppose that your data showed that smoking causes cancer. What action would you take?We would inform people of the risks.7. Suppose that your data did not show that smoking causes cancer. What action would you take?We would take no action since there are no risks. We could fake data so that people quit that dirty habit (kidding).8. Why do we take a sample from the population?9. What are we hoping that our data will do for
