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
