Brakes Case Study Concerning the normality assumption which is required on each population, based on the information given, is there any way that we can CHECK that this assumption is legitimate in this situation? Question 2 options: Yes, we can take the data provided and make histograms of each sample and check for rough normality Yes, we can pool the two standard deviations provided in this problem, so that justifies the normality assumption. No, not really. But, if we had the individual data points per sample, the best thing we could do is create dot plots and investigate their shape. No, the CLT applies to the two sample t-test. So, there is no need in this particular case study to check the normality assumption
