Population 1: m 1 = Mean age of Purchasers of Crest Toothpaste

Population 2: m 2 = Mean age of Non-Purchasers of Crest Toothpaste

1. Formulate the appropriate null and alternative hypotheses to test if the data presents sufficient evidence to conclude there is a difference in the mean age of purchasers and non-purchasers. Make sure your statements are in both sentence and numerical form.

Ho: m 1 = m 2
Ha: m 1 Not Equal To m 2

Null Hypothesis: The mean age of purchasers of Crest toothpaste is equal to mean age of non-purchasers of Crest Toothpaste

Alternative Hypothesis: The mean age of purchasers of Crest toothpaste is not equal to mean age of non-purchasers of Crest toothpaste.
