Sean is thinking about using seawater to water his plants. Sean places 10 spider plants near a window for 20 days. Each day, he waters 5 plants with 10 mL of seawater and five plants with 10 mL of fresh water. He measures their height before and after the 20 days. Shown below is a table of Sean’s results. | Plants receiving | Average Initial Height (in cm) | Average Final Height (in cm) | |------------------|-------------------------------|------------------------------| | Seawater | 12.1 | 12.9 | | Fresh water | 12.4 | 14.7 | Based on these results, which of the following could Sean conclude?
