Test for a difference between the product weights for the two lines. Use α = 0.05.
State the null and alternative hypotheses.
Ho: Median for line 1 - Median for line 2 < 0
H₂: Median for line 1 Median for line 2 = 0
Ho: Median for line 1 - Median for line 2 ≤ 0
H₂: Median for line 1 - Median for line 2 > 0
O Ho: The two populations of product weights are not identical.
H₂: The two populations of product weights are identical.
Ho: Median for line 1 - Median for line 2 ≥ 0
H₂: Median for line 1 - Median for line 2 < 0
O Ho: The two populations of product weights are identical.
H₂: The two populations of product weights are not identical.
Find the value of the test statistic.
W = 17
X
Find the p-value. (Round your answer to four decimal places.)
p-value = 0.0050 X
State your conclusion.
O Do not reject Ho. There is sufficient evidence to conclude that there is a significant difference between the product weights
for the two lines.
O Do not reject Ho. There is not sufficient evidence to conclude that there is a significant difference between the product
weights for the two lines.
O Reject Ho. There is not sufficient evidence to conclude that there is a significant difference between the product weights for
the two lines.
● Reject Ho. There is sufficient evidence to conclude that there is a significant difference between the product weights for the
two lines.
