Do individuals walk at different speeds depending on whether they are departing or arriving at the
α=0.05
level of significance? Let
μ1
represent the mean speed of people departing and
μ2
represent the mean speed of people arriving.State the null and alternative hypothesis.
H0:
μ1=μ2H1:
μ1>μ2H0:
μ1=μ2H1:
μ1≠μ2H0:
μ1<μ2H1:
μ1>μ2H0:
μ1=μ2H1:
μ1<μ2Determine the P-value for this hypothesis test.
P-value=nothing
(Round to three decimal places as needed.)Choose the correct conclusion.
Reject

sufficient evidence at the
α=0.05
level of significance to say that travelers walk at different speeds depending on whether they are arriving or departing.Reject
