- Data Management Kiran was looking to purchase a new dishwasher for her kitchen, and wondered if there was any relationship between the cost of the dishwasher and the amount of energy required to operate the dishwasher. While researching dishwashers she compiled the following data about the annual energy requirement in kilowatt-hours (kWh) for various models of dishwashers. Energy Required (kWh) 290 320 430 499 515 549 575 595 595 660 710 1799 Cost of Dishwasher ($) 1120 1045 960 890 910 950 890 900 850 800 685 700 1. Graph the data (You may use excel, DESMOS, by hand, any tool you want) 2. Determine the equation of the line of best fit and the correlation coefficient. Add the line of best fit to the graph. (This is easiest done in Excel) 3. Describe the relationship in the data. Hint: refer to the correlation coefficient. 4. Using your line of best fit; predict how much Kiran can expect to pay for a dishwasher that has an annual energy requirement of 400 kWh 5. What type of Cause and Effect relationship do you believe this data shows? Explain
