Project 2
NAME:
For all problems, show your calculations or your work in Excel and explain your thinking. There is a video
included in this week’s learning which can be used to help with your calculations.
1.
A college professor distributed a bag of M&Ms to each student in their class. Your bag is shown below.
a)
Calculate the percentage of each color and show your calculations in the table. Write your answer as a
decimal and round to 3 decimal places. (Example: 7/33 = 0.212 is how that should look).
The professor asked students to submit their M&M totals in a class poll. The data is below. Note: 6 students who were in
class did not submit their totals in time to be counted (maybe they were busy eating the M&Ms).
b)
Calculate the mean and median for the total M&Ms using the 20 numbers above. Show your calculations or
add a screenshot of your work in Excel.
c)
Which measure for the average should the professor use to describe the average number of M&Ms? Why?
d)
Suppose the 6 students who didn’t submit their total in class all had 50 M&Ms in their bag. How would that
change the mean number of M&Ms? How would that change the median number of M&Ms? Write a
sentence to explain your thinking.

Project 2
In addition to collecting total numbers, the professor collected counts for each color. The totals are below. Show your
calculations for each color in the table, rounded to 3 decimal places.
Qty
86 Brown
Qty
88 Red
Qty 286 Blue
Qty 137 Green
Qty 106 Yellow
Qty 320 Orange
e)
Compare the percentages from your bag to the percentages for the entire class. What changes do you
notice? Which colors stayed the most consistent?
f)
A 5-pound bulk bag of M&Ms holds approximately 2700 pieces. How many of each color should we expect to
find in the bag based on the results of the percentages
from the entire class?
Show your calculations for
each color in the table and round to 3 decimal places.
g)
Suppose a bag of M&Ms is dumped on the table and you count 32 orange pieces.
Approximately how many
M&Ms do you expect to be in the entire bag based on the percentages of the entire class?
Write a sentence
to explain your thinking and your calculations.
