Breathe deeply: Breathing rates, in breaths per minute, were measured for a group of ten subjects at rest, and then during moderate exercise. The results were as follows: Subject Rest Exercise 1 14 35 2 17 36 3 19 35 21 39 17 34 16 31 19 32 15 40 20 37 20 30 4 5 6 7 8 9 10 Send data to Excel Part: 0 / 2 Part 1 of 2 (a) Construct a 95% confidence interval for the mean increase in breathing rate due to exercise. Let d represent the breathing rate after exercise minus the breathing rate at rest. Use the TI-84 Plus calculator and round the answers to one decimal place. A 95% confidence interval for the mean increase in breathing rate due to exercise is < <0.
