Question

The box plot below shows the total amount of time, in minutes, the students of a class surf the Internet every day:


A box plot is shown. The left-most point on the plot is 20 and the right-most point is 95. The box is labeled 37.5 on the left edge and 60 on the right edge. A vertical line is drawn inside the rectangle at the point 50.


Part A: List two pieces of information that are provided by the graph and one piece of information that is not provided by the graph. (4 points)


Part B: Calculate the interquartile range of the data, and explain in a sentence or two what it represents. (4 points)


Part C: Explain what affect, if any, there will be if an outlier is present. (2 points)

Answer 1

Well, you need to know the atomic weight of Platinum (Pt) and the number of atoms per mole. The answer to the former is 195.084 g/mole and the latter is 6.023 * 10^23 atoms/mole. Then, multiply everything as shown below:

Number of atoms = (1 g) * (1/195.084 g/mole) * 6.023 * 10^23 atoms/mole

Number of atoms = 3.087 * 10^21 atoms

Note, I’ve included units on everything and you can see that they all cancel except for atoms. Dragging the units along can be a pain but it is a great way to check that they way the numbers are being combined is

Answer 2

Answer:

this is for A Part A: it shows that the least amount is 37.5 minutes 

           it shows the most amount of time is 60 minutes 

         one thing it does not show is how many students where in the class
