Saturday: cookies

Today I made cookies for an event at church and put two M&Ms on each one. I wondered what the red-red, green-red, and green-green distribution was, so I counted.

Red-red: 19 (23%)
Green-red: 50 (60%)
Green-green: 15 (17%)

This tells me I need a larger sample size. Or possibly that there is a higher percentage of red M&Ms. But probably that I need to make more cookies.

I ran a quick chi-square test for you. Based on your data, there is no significant deviation from the expected frequencies in your m&m color combinations (p=.18)

All colors equally represented!
