Breathing Patterns Research psychologists measured the baseline breathing patterns—the total ventilation (in liters of air per minute) adjusted for body size—for each of n = 30 patients, so that they could estimate the average total ventilation for patients before any experimentation was done. The data, along with some MINITAB output, are presented here:
a. What information does the stem and leaf plot give you about the data? Why is this important?
b. Use the output to construct a 99% confidence interval for the average total ventilation for patients.
