denoted by Δ0.
• If we hypothesize that the population means we are comparing
are equal, set Δ0 = 0. The null hypothesis would be 𝐻0: 𝜇1−
𝜇2 = 0 (or equivalently 𝐻0: 𝜇1 = 𝜇2.)
• We may hypothesize that one population mean is larger than
another by some amount. The null hypothesis would be
𝐻0: 𝜇1− 𝜇2 = Δ0 in this case
Q2 QUESTION 2 OF 47

RESPONSE
tv=(xbar1-xbar2)-D0/sqrt(s1^2/n1+s2^2/n2)
Q3 QUESTION 3 OF 47
t assumptions and conditions
RESPONSE
• Independence: Sampled observations are independent
• Randomization: Data come from random sample
• 10% Condition: Sample is no larger than 10% of the population
