Consider the following competing hypotheses and accompanying sample data drawn independently from normally distributed populations. (You may find it useful to reference the appropriate table: z table or t table)

H0: μ1 − μ2 ≥ 0
HA: μ1 − μ2 < 0

x−1x−1 = 267 x−2x−2 = 295
s1 = 37 s2 = 31
n1 = 11 n2 = 11
