Volume of air inspired or expired with each normal breath is known as :Inspiratory capacityTotal Lung capacityTidal volumeResidual volume

After the expiration of a normal tidal volume, a subject breathes in as much air aspossible. The volume of air inspired is thea) inspiratory reserve volume.b) vital capacity.c) inspiratory capacity.d) d. total lung capacity.e) functional residual capacity.

The amount of air that normally enters the lungs during quiet breathing: Group of answer choicestotal lung capacityresidual volumevital capacitytidal volume

The volume of air remaining in the respiratory passages and lungs after forceful expiration is called:

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
