2. What is the mean of this data?
3. What is the mode of this data?
4. What is the median of this
5. If the standard deviation for this data
group was 0.45 g/cm³, how far from the mean is the most extreme value of
Please use the following graph of Mass vs Volume to answer the next series of questions.
1. Which variable belongs on the x-axis?
on the y-axis?
2. What are the
co-ordinates of two gridpoints?
3. Calculate the
slope of this line.
4. If mass is
measured in grams and volume in cm³, what are the units for the slope of this line? What
physical property does this slope represent?
5. Calculate the
y-intercept for this line.
6. What is the
equation for this line?
7. Using the
equation in #6, interpolate the value for the mass when the volume is 4 cm³.
8. If 20 cm³ of a
material has a measured mass of 125 grams, would you suspect it of being made of the same
material as the items graphed above?
