Does the potency of drug reduce after one year in storage? To test this, researchers plan to compare the average potency of a sample of recently produced bottles of the drug with the average potency of a sample of bottles of the drug that have been stored for a year. They will test for evidence that the mean potency score for the fresh drug (µ1) is higher than the mean potency score for the stored drug (µ2). Based on the information provided, which of the following sets of hypotheses is appropriate for the test? Hint: We first cover inference for a difference in means in Section 6.4. Select one: a.H0: μ1 - μ2 ≤ 0, Ha: μ1 - μ2 = 0 b.H0: μ1 - μ2 = 0, Ha: μ1 - μ2 > 0 c.H0: μ1 - μ2 = 0, Ha: μ1 - μ2 < 0 d.H0: μ1 - μ2 = 0, Ha: μ1 - μ2 ≠ 0

Question
Does the potency of drug reduce after one year in storage?
To test this, researchers plan to compare the average potency of a sample of recently produced bottles of the drug with the average potency of a sample of bottles of the drug that have been stored for a year.
They will test for evidence that the mean potency score for the fresh drug (µ1) is higher than the mean potency score for the stored drug (µ2).
Based on the information provided, which of the following sets of hypotheses is appropriate for the test?
Hint: We first cover inference for a difference in means in Section 6.4.
Select one:
a.H0: μ1 - μ2 ≤ 0, Ha: μ1 - μ2 = 0
b.H0: μ1 - μ2 = 0, Ha: μ1 - μ2 > 0
c.H0: μ1 - μ2 = 0, Ha: μ1 - μ2 < 0
d.H0: μ1 - μ2 = 0, Ha: μ1 - μ2 ≠ 0
