1. Camry Mileage: Research Context: With 95% confidence, we wish to estimate (if possible) the mean highway mileage for all 2003 Toyota Camrys. Provide a 95% Confidence Interval, if possible, for the mean highway mileage for all 2003 Toyota Camrys. Further, with 95% confidence, we wish to know, using hypothesis testing, if the mean highway mileage for all 2003 Toyota Camrys is greater than 30 mpg.
Use the following random sample of n=20 highway mileages (Column C1 in HW1DATA.mtw) for 2003 Toyota Camrys. Make certain you outline which statistical procedure(s) you are using and evidence that the technique(s) you are using is/are valid. If it is not possible to perform this analysis, simply say so and why. For what it is worth, a non-parametric procedure (one sample wilcoxon) that is beyond the scope of this course is used in STA-583.
