We have learned many statistical analysis techniques to help make sense of data and help guide decision-making. in this homework problem, we ask that you use your statistical knowledge to make sense of the cars data set. This data set contains information on a random sample of 500 cars from 2001. It contains the following variables: 0 class : vehicle class (car or tmck/SUV) . fuettype : fuel type (gas or diesel) - engine : engine size (in liters) - cylinder : number of cylinders - consumption : fuel consumption (in liters per 100km) - emissions : 002 emissions (in grams of 002 per km) Step 1: Propose a question that you would like to explore using the ca rs data set. Step 2: Using the HWOQ project in our RStudio Cloud workspace, explore the data set and perform the appropriate statistical analysis to answer your proposed question. Note: You may assume all assumptions are met to perform the statistical analysis. Step 3: Using the output you generate, answer your proposed question. Here is a reminder of all the statistical analysis techniques you have learned this semester in Stats 250: - One-sample z-procedures for a population proportion o One-sample t-procedures for a population mean - Two-sample t-prooedures for the comparison of two population means - Two-sample z-procedures for the comparison of two population proportions o Paired tprocedures for a population mean of differences 0 Simple linear regression - Chi-squared test of goodness of fit - Chi-squared test of independence Your answer should include the following: 1. A clear statement of the question of interest (remember, you are coming up with this question). 2. Appropriate statistical analysis (as part of your work. you should include appropriate graphical displays or tables and Ft output corresponding to the appropriate statistical inference procedure). 3. An answer to the question you proposed. Question 5 Answer |~ Student Log Out Co
