Resting heart rate is the number of times your heart beats per minute when it is at rest and the best time to measure your resting heart rate is in the morning after a good night's sleep but before you get out of bed. What is considered a normal resting heart rate depends upon your age and activity level, but generally a resting heart rate of 60-100 beats per minute (BPM) is considered to be a normal range for a healthy adult. After sitting half-way through an introductory statistics class session, a group of students measured their heart rates. This group of students is considered to be representative of students attending the same college. We will investigate whether introductory students at this college have heart rates in the normal adult range and because sitting in class is not exactly resting, let's posit that 80 BPM is a reasonable resting pulse rate to expect. A one-sample t test will be used on a subset of the data to determine whether introductory statistics students at this college have an average heart rate of 80 BPM after sitting halfway through class. Use a significance level of a = 0.05. The first five rows of the data look like this. t Gender Female Female Male Female Female BPM Variable 72 66 Import the dataset into SALT for analyzing 72 54 60 After you have clicked the tab for your selected topic and read the problem, answer the questions below.
