A taxi company decide to put this on to test with data collected from 40 most recent purchased cars to the company. They randomly split the 40 cars into two groups where 20 cars only used premium gasoline and remaining 20 used regular gasoline. One month maintenance cost was recorded for each car. Below shown is partial data with some summary statistics. Part of the data with some summary statistics is displayed below. Please note that some information may or may not be relevant. Premium Regular Diff 1000 1119 -119 1095 1046 49 . . . 1350 914 436 Mean 2225.05 998.6 112.48 Standard Deviation 131.58 226.45 154.72 Are the two samples: Premium and Regular, independent or dependent? Explain your answer From the provided plots: (A), (B) and (C), clearly state which plot/plots you would use to check any assumptions. Do you see any serious violations of those assumptions? Explain your answer without simply saying yes or no. Company is interested in testing if the true mean maintenance cost different based on the type of gasoline used.
