6. [-110.41 Points] DEVORESTAT9 12.1.0035. ASK YOUR TEACHER Bivariate data often arises from the use of two different techniques to measure the same quantity. As an example, the accompanying observations on X = hydrogen concentration (ppm) using a gas chromatography method and y = concentration using a new sensor method were read from a graph in an article.

Do the two methods appear to be measuring roughly the same quantity? Explain your reasoning. O The points fall very close to a quadratic line with xintercepts of approximately 0 and 225. This suggests that the two methods are producing substantially different concentration measurements. O The points fall very close to a straight line with an y-intercept of approximately 125 and a slope of about 0. This suggests that the two methods are producing substantially the same concentration measurements. 0 The points fall very close to a straight line with an x-intercept of approximately 0 and a slope of about 1. This suggests that the two methods are producing substantially the same concentration measurements. O The points fall very close to a quadratic line with xintercepts of approximately 0 and 225.
