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. Gender BPM Female 54 Female 60 Female 48 Female 48 Male 66 Import the dataset into SALT for analyzing. A USE SALT ter you have clicked the tab for your selected topic and read the problem, answer the questions below. »» Use SALT to summarize the data and fill in the following table, rounding values to four decimal places as needed. Sample Size Standard deviation Mean Variable We need to verify the assumptions for using the one-sample t test before analyzing this dataset. First the observations in the sample must be randomly selected from the population or the sample should be selected in such a way that the sample is representative of the population.
