Extracted text: We can assume that the heart rate of healthy spanish men follows a normal distribution with mean 80 beats/minute and standard deviation 10 beats/minute. Next two questions are about the heart rate of healthy Icelandic men. A heart rate faster then 100 beats/minute is classified as tachycardia. If a healthy spanish individual is chosen at random, what is the probability that he is measured with tachycardia? 1. 5.8 % 2. 2.3 % 3. 97.7 % 4. 94.2 % 5. R-command: How fast needs the heartbeat of a healthy spanish man to be if he should be among the 10 % of healthy spanish men with the fastest heartbeat? 1. 102.8. 2. 77.2. 3. 92.8. 4. 67.2. 5.
