there is a significant difference in the time required by the three methods.
State the null and alternative hypotheses.
O Ho: Not all populations of times are identical.
H: All populations of times are identical.
Ho
: All populations of times are identical.
H₂:
: Not all populations of times are identical.
O Ho: Median₁ = Median2
= Median3
H: Median > Median2 > Median3
O Ho: Median₁ = Median2
= Median 3
H: Median, Median2 # Median 3
O Ho: Median, Median2 # Median 3
Ha Median₁ = Median2 = Median3
Find the value of the test statistic. (Round your answer to two decimal places.)
