We are interested in determining whether or not the variances of the sales are equal for two small grocery stores. A sample of 12 days of sales at each store indicated the following.

Store A	Store B
n₁ = 12	n₂ = 12
s₁ = $120	s₂ = $100

Are the variances of the populations (from which these samples came) equal? Use = 0.05. (Let ₁ be the population standard deviation for store A and ₂ be the population standard deviation for store B.)

State the null and alternative hypotheses (in dollars²). (Enter != for as needed.)

H₀:??
