An article reported data from a study in which both a baseline gasoline mixture and a reformulated gasoline were used. Consider the following observations on age (yr) and NOx emissions (g/kWh): Engine 1 2 3 4 5 6 7 8 9 10 Age 0 0 2 11 7 16 9 0 12 4 Baseline 1.74 4.38 4.04 1.23 5.30 0.58 3.35 3.44 0.73 1.23 Reformulated 1.85 5.93 5.52 2.67 6.54 0.76 4.94 4.87 0.69 1.39 Construct scatter plots of the baseline NOx emissions versus age. Construct scatter plots of the reformulated NOx emissions versus age. What appears to be the nature of the relationship between these two variables? As age increases, emissions also increase.As age increases, emissions decrease. There is no compelling relationship between the data.

Based on the data of air pollution in Los Angeles in 2019, the Environmental Protection Agency (EPA) decided to publish a new stricter regulation effective in January 2020 to reduce hydrocarbon pollution. EPA wants to evaluate whether the new regulation makes significant differences in reducing pollution. EPA collects data of monthly hydrocarbon pollution level as follows: Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec 2019 7.3 6.0 5.4 5.9 3.9 5.7 6.9 7.6 6.3 5.8 5.1 5.9 2020 5.3 6.1 5.6 5.7 3.7 4.7 6.1 7.2 6.4 5.7 4.9 5.8
