a. Assuming that the population variances from the​ 30-second ads and the​ 60-second ads are​ equal, is there evidence of a difference in the mean score between the two types of​ ads? Use
α=0.02.
 
Let
μ1
be the mean score for the​ 30-second ads and
μ2
be the mean score for the​ 60-second ads. Determine the hypotheses. Choose the correct answer below.
 
 
A.
H0​:
μ1≥μ2
H1​:
μ1<μ2
 
B.
H0​:
μ1=μ2
H1​:
μ1≠μ2
Your answer is correct.
 
C.
H0​:
μ1≠μ2
H1​:
μ1=μ2
 
D.
H0​:
