Independent random samples from two regions in the same area gave the following chemical measurements (ppm). Assume the population distributions of the chemical are mound-shaped and symmetric for these two regions. Let Hi be the population mean for X1 and 2 be the population mean for X2 . Suppose the confidence interval for H1 - P2 for a specific level of confidence is - 30.77 to 2.25. Does the interval consist of numbers that are all positive? all negative? or different signs? At the given level of confidence, is one region more interesting than the other from a geochemical perspective? The interval contains only positive numbers. We can say at the required confidence level that one region is more interesting than the other. O The interval contains both positive and negative numbers. We can say at the required confidence level that one region is more interesting than the other. The interval contains both positive and negative numbers. We cannot say at the required confidence level that one region is more interesting than the other. The interval contains only negative numbers. We can say at the required confidence level that one region is more interesting than the other. O The interval contains only positive numbers. We cannot say at the required confidence level that one region is more interesting than the other.
