Several local homeowner associations commissioned a study to determine if a riding mower
was significantly louder than a power push mower.
Given the information gathered by the associations, which of the following is the correct
conclusion, if using a significance level of 0.02?
The hypotheses are Ho A. H₁ ₂. With a test statistic of t = 2.4746 and a P-value of
0.0203, you must fail to reject the null hypothesis.
The hypotheses are Ho H-M. M₁4 > 4₂. With a test statistic of -2.4746 and a P-value of
0.0101, you must reject the null hypothesis.
The hypotheses are H₁A=M. H: 4<. With a test statistic of -2.4746 and a P-value of
0.0101, you must fail to reject the null hypothesis.
The hypotheses are H₁ 4² 4.8₁ 4 > 4. With a test statistic of := 2.4746 and a P-value of
0.0203, you must reject the null hypothesis.
