As part of a study investigating symptoms mountain climbers experience at high altitudes, researchers looked at the skeletal muscle tissue of a random sample of climbers. Each trained for two weeks on a. bicycle, either at a normal oxygen supply or under hypoxic conditions corresponding to an altitude of 13,000 it. They also were assigned to train at either a. high or low level of energy expenditure. The percent change in vascular endothelial growth factor mRNA was measured and all relevant assumptions were conrmed. Below is a table of their results: Effect F pvalue 02 Supply 16.05 <: energy expenditure supply exp. a. if the error degrees of freedom="60," how many climbers were there in this study opt b. eedom are for each main effects and interaction effect par c. write an appropriate conclusion between oxygen on growth factor mrna below is plot analysis. explain above conrms results term anova table. figure eu him low eh39>
