This project, part of MAT10251 Statistical Analysis, examines the prices of used Holden Commodore (6-cylinder) cars from 2014 and 2015 in Queensland. The analysis, based on a random sample of 40 cars, determines the average price, which is approximately $25,710, with a minimum of $17,900 and a maximum of $32,990. The data distribution is approximately normal, allowing the use of the mean as a central tendency measure. The project provides insights into the range, standard deviation, and percentiles of the car prices, offering valuable information for potential buyers. The findings suggest that 50% of the car prices are above the median value of $25,990, 25% below $22,987 and 25% above $28,840. The analysis provides a comprehensive overview of the car prices based on the statistical measures.
