Three labs were contracted to measure the concentration of a 5.50 ppm Ca2+ standard solution. They each measured the solution 3 times, and their results are as follows: Measurement 1 Measurement 2 Measurement 3 5.47 ppm 5.54 ppm 5.50 ppm Laboratory 1 Laboratory 2 5.32 ppm 5.44 ppm 5.56 ppm Laboratory 3 5.61 ppm 5.62 ppm 5.60 ppm Select ALL of the TRUE statements about the meassurement capabilities of these labs. Lab #3 was the most precise. Lab #1 was the most precise. Lab #1 was the most accurate. OLab #2 was the most precise. Lab #2 was the most accurate. Lab #3 was the most accurate.
