Question

The respiratory system can be a limiting factor in maximal exercise performance. Researchers studied the effect of two breathing frequencies on both performance times and several physiological parameters in swimming. Subjects were 10 male collegiate swimmers. Here are their times in seconds to swim 200 meters at 90% of race pace when breathing every second stroke in front crawl swimming.

151.6	165.5	159.4	164.3	175.2
173.4	178.2	174.5	164.1	171.4

Calculate the mean of the data. (Enter your answer to two decimal places.)

Answer 1

Given that, 151.6 165.5 159.4, 164.3 175-2, 173.4. 178.2 . 174.5 104.1. 171.4 ime need to find mean of the data. mean c = Total of all observation No. of observation. CEx. (3) = 151.6 + 165.5 +...... 171.4 = 1677.6 10 mean ( ) = 167.76
