0 CI = {4.0121, 4.9879} Q6: Conclude your findings. What could the researcher conclude about the effect of the two drug concentrations on muscle relaxation? From the confidence level we can say that there is a statistical significance between the two means as it does not include a 0 in the interval. To re-assess we can find the t-statistic (done below), and this also confirms that this there is a statistical significance because the t-statistic is larger than the t-critical value of 2.05. 0 Tstatistic = difference in means/standard error 0 tstatistic = 4.5/0.238 = 18.907 Q7: Can the researcher apply the results on female long-distance runners? Elaborate your answer. Yes the researcher can apply the results on female long-distance runners. As explained in Q6 above there is a statistical significance between the two means. It has also been confirmed by finding the tstatistic where the tstatistic is quite larger than the tcritical value and this could be evidence that there is a greater significance in that the high concentration of muscle relaxant does have a larger effect than low concentration of muscle relaxant, the net difference is relatively large for each participant
