A: Assumptions Since quantitative information was collected from each object, we need to check the following conditions: Check all that apply. Or1 > 10 and $2 2 10 On - 1 2 10 and n2 - 22 2 10 O M 2 20n, and N2 2 20n2 O The samples are independent O The samples are dependent Normal population of differences or at least 30 pairs of data Normal populations or n1 2 30 and n2 2 30 No outliers in the differences No outliers for each group O o is unknown for each group o is known for each group Check those assumptions: 1. There were two measurements taken on the same object, so these samples are independent 2. Is the value of o unknown for each group? |Now 3. Are there any outliers in the differences? Yes, the normal probability plot shows outliers 4. n = which is
