A survey was carried out involving a sample of 73 patients, among 15and 20 years old, from a certain hospital. Each of these patients underwent a series of clinical examinations, including your heart rate. Healthy people in this age group they beat between 60 and 90 times per minute. Knowing that the sample mean and the population standard deviation are 87 and 20, respectively, calculate the probability the mean of the patients in the sample to be within the heart rate range?
