Myocardial blood flow (mbf) was measured for two groups of subjects after 5 minutes of bicycle exercise. the normoxia ("normal oxygen") group was provided normal air to breath whereas the hypoxia group was provided with a gas mixture with reduced oxygen, to simulate high altitude. the results (ml/min/g) are as follows and are plotted below:
in the table. use a=0.05
normoxia / hypoxia
3.45 6.37
3.09 5.69
3.09 5.58
2.65 5.27
2.49 5.11
2.33 4.88
2.28 4.68
2.24 3.50
2.17
1.34
10 8 n
2.51 5.14 y-hat
0.60 0.84 s
use a t-test to investigate the effect of hypoxia on mbf. assume you are looking for a difference.
