Let's calculate the proportion of each color of M&M from our bag and compare it to what the website says we should have gotten. We see that our total sample size is now, n = 200.Â
There are 27 Brown M&M's, 35 yellow M&M's, 28 Red M&M's, 46 Blue M&M's, 30 Orange M&Ms and 34 Green M&M's in our bag of M&M's.
- In a Word document, answer the following questions:
- Which colors are higher, lower, or the same proportion as the website?
- How close are our numbers to what the company says we are supposed to get?
- Is any color an outlier?
- Do you think the Mars Company favors one color over another? Why or why not?
- When comparing our proportions to the website's proportions do you think our calculations are an over prediction, under prediction or the same prediction as what to expect from a bag of M&Ms. Why?
Using Excel, construct a Histogram with the frequency numbers of each color.
- Make sure there are appropriate labels on your histogram.
- Paste the histogram into your Word document.
Using Excel, construct a pie chart using the proportions from each color.
- Make sure there are appropriate labels on your pie chart.
- Paste the pie chart into your Word document.
Answer the following questions about the charts you've constructed.
- What do you see?
- What is the shape and distribution?
- Which color has the highest proportion and which color has the lowest proportion and what are they?
Submit both the Excel spreadsheet and the Word document.
