Assume that the data contained in the file represents a random sample of cars from Japan, the USA, and Other countries. Perform the following analysis. 1. Sort, or Arrange, the data so that you have Gas Tank Size by Type of car. Note the Type of car is Sporty, Compact, Medium, and Large. You will need a column for each Type. You can do this using the Sort feature and then copy and paste into separate columns for each Type, or you could use a pivot table with Model as a row variable, Type as the column variable, and Gas Tank Size as the summary value. Once you have sorted and arranged the Gas Tank Size values by Type, Copy/Paste your sorted table to a new worksheet. 2. Produce a boxplot of Gas Tank Size for each Type of car. Briefly comment on the findings paying attention to the spread and the center of each Type of car's distribution as shown by the boxplot. 3. Conduct the appropriate test to determine if there is a difference in mean Gas Tank Size by Type of car. Use a level of…
