3. Does the price of an appliance, specifically a washing machine, convey something about its quality? Which variables did you use in arriving at your answer?

Does the price of an appliance convey something about its quality?
Washers are classified as top-load high efficiency (HE), top-
load agitator, and front-load washers. The best front-loaders clean better and are gentler than the best HE top-loading washing machines while using less water. Front-loaders take longer than HE top-loaders but spin faster, extracting more water, and reducing dryer time. Fifty-four different front-loading washers were ranked19 on characteristics ranging from an overall satisfaction score, washing performance (x1), energy efficiency (x2), water efficiency (x3), gentleness (x4), noise (x5), vibration (x6), capacity (x7), and cycle time (x8). Variables x1 through x6 are converted scores for pictograms where 5 5 (excellent), 5 4 (very good), 5 3 (good), 5 2 (fair) and 5 1 (poor). Use a statistical package to explore the relationships between various pairs of variables in the table.
