A chemistry student measures the density of an unknown liquid by dividing its mass by its volume. The measured values are 18.475 g for the mass and 12.3 mL for the volume. The student enters the calculation into the calculator and gets: 18.475 g12.3 mL=1.5020325 g/mL\frac{18.475\text{ g}}{12.3\text{ mL}} = 1.5020325\text{ g/mL} However, the student reports 1.5020325 g/mL because “the calculator never lies.”  What is the correctly reported density, considering the rules for significant figures?

You are doing an experiment on how well a certain teaching method is working. The first teaching method is the “Fixed Mindset” teaching method that teaches students that their success is all “Innately driven” and the second teaching method is the “Growth Mindset” teaching method that teaches students that their success is primarily a product of “work and growth.” After taking an exam, here are your students scores: Fixed: 10, 10, 9, 8, 8, 4, 1, 1, 2, 3 Growth: 10, 9, 8, 7, 8, 8, 6, 7, 7, 8 Put both of these variables into RStudio and find the mean of each group. Take a screenshot of the work and upload the file here. Include your name, upload only one screenshot, and only jpeg.
