Arby's
McDonald's
n₁ = 15
n₂ = 12
x₁ = 60 mg
s₁ = 3.59 mg
x₂ = 70 mg
X.
$₂ = 2.41 mg

In this problem, assume that the distribution of differences is approximately normal. Note: For degrees of freedom d.f. not in the Student's t table, use the closest d.f. that is smaller. In some situations, this choice of d.f. may increase the P-value by a small amount and therefore produce a slightly more "conservative" answer.In the following data pairs, A represents birth rate and B represents death rate per 1000 resident population.
