Will Lentil’s new slogan change help her pull ahead?

BIG QUESTION

3 possible outcomes:

1. The slogan makes no difference; Lentil and Lima are still tied2. Lentil pulls ahead3. The slogan backfires (some think it offensive) and Lentil pulls ahead

1. Work in groups of 4 (I’ll put you in groups)2. Pull out 10 beans at a time3. Record how many reds you get in the proper column4. For example, if you get 6 red beans out of 10, mark a

tally here.

10% Rule for Sampling without Replacement

Note: it is not necessary to replace each bean individually after it is sampled.

500 beans in each bag: samples of up to 50 without replacement would still be appropriate.
