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. Region I: *1; n =12 981 726 686 496 657 627 815 504 950 605 570 520 Region II: x2; n2 =16 1024 830 526 502 539 373 888 685 868 1093 1132 792 1081 722 1092 844 Let 41 = 678 be the population mean and o1= 164 be the population standard deviation for x1. Let 42 = 812 be the population mean and o2= 239 be the population standard deviation for x2. Determine and examine the 90% confidence interval for H1-42. Does the interval consist of numbers that are all positive? all negative? or different signs? At the 90% level of confidence, is one region more interesting that the other from a geochemical perspective? 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 only positive numbers. We cannot say at the required confidence level that one region is more interesting than the other. The interval contains only positive numbers. We can say at the required confidence level that one region is more interesting than the other. The interval contains only negative numbers. We cannot 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.
