Effects of physical training A study was conducted to investigate the effects of physical training. Sample data from ten subjects is listed below, with all weights expressed in kilograms. (See "Effect of resistance training on potential determinants of VO2 during heavy exercise," by Casaburi et al., Journal of Applied Physiology, Vol. 62, No. 1.) What test should be used? Complete all necessary steps to perform the test. Is there sufficient evidence to conclude that there is a difference between pre- and post-training weights? What do you conclude about the effect of training on weight? Construct a 95% confidence interval for the mean of the differences between the weights before and after training. Pre-training: 99 57 62 69 74 77 59 92 70 85 Post-training: 94 57 62 69 66 76 58 88 70 84
