Question #2025156: Hypothesis Testing

Question: Q1: Following the machining process the components are to be hardened and then tempered. As part of the design process a sample of eight components was tempered at different temperatures with the following results:

Temperature °C Hardness Vpn
240 550
275 532
300 525
335 514
360 474
395 470
420 458
455 446

Draw a scatter diagram of this data and calculate the correlation coefficient. Comment on the nature of the relationship between temperature and hardness.
