Lung volume, also known as lung capacity, is the volume of gas in one’s lungs at a given time during the respiratory cycle. Lung volume is measured in metric litres (L).You are a sports scientist and performed an experiment investigating the effect of exercise on lung volume. 8 participants were initially chosen, and asked to jog for 10 minutes and their average lung volumes in that time interval was recorded. The participants then followed a strict exercise routine for 6 months. At the end of the 6 months, the participants were asked again to jog for 10 minutes and their average lung volumes were recorded again. The results are below:Participant IDMeasurementAvg 10-minute Lung Volume (L)1Initial10.0852Initial3.9763Initial5.0404Initial7.9105Initial9.0586Initial2.5027Initial7.5428Initial5.8031Post7.1502Post7.2573Post9.6684Post5.6245Post7.3676Post6.4627Post5.1608Post10.924The data can be read into R using the following code:initial = c(10.085, 3.976, 5.040, 7.910, 9.058, 2.502, 7.542, 5.803) post = c(7.150, 7.257, 9.668, 5.624, 7.367, 6.462, 5.160, 10.924)Select the most appropriate test to use in this setting.Group of answer choicesPaired t-testANOVAClassical two-sample t-testWelch two-sample t-test

Main articles: Breathing and Lung volumesThe lungs expand and contract during the breathing cycle, drawing air in and out of the lungs. The volume of air moved in or out of the lungs under normal resting circumstances (the resting tidal volume of about 500 ml), and volumes moved during maximally forced inhalation and maximally forced exhalation are measured in humans by spirometry.[12] A typical adult human spirogram with the names given to the various excursions in volume the lungs can undergo is illustrated below (Fig. 3):
