Suppose the following data are product weights for the same items produced on two different production lines.
| Line 1 | Line 2 |
|---|---|
| 13.9 | 13.8 |
| 13.6 | 14.5 |
| 14.0 | 14.4 |
| 13.2 | 14.0 |
| 13.3 | 14.9 |
| 13.4 | 13.1 |
| 13.7 | 14.3 |
| 13.9 | 14.6 |
| 12.2 | 14.1 |
| 14.3 | 14.7 |
| 15.0 | |
| 14.2 |
Test for a difference between the product weights for the two lines. Use = 0.05.State the null and alternative hypotheses.H0: Median for line 1 Median for line 2 < 0 Ha: Median for line 1 Median for line 2 = 0H0: The two populations of product weights are identical. Ha: The two populations of product weights are not identical. H0: The two populations of product weights are not identical. Ha: The two populations of product weights are identical.H0: Median for line 1 Median for line 2 0 Ha: Median for line 1 Median for line 2 > 0H0: Median for line 1 Median for line 2 0 Ha: Median for line 1 Median for line 2 < 0Find the value of the test statistic.
W =
Find the p-value. (Round your answer to four decimal places.)p-value = State your conclusion.Do not reject H0. There is sufficient evidence to conclude that there is a significant difference between the product weights for the two lines.Reject H0. There is not sufficient evidence to conclude that there is a significant difference between the product weights for the two lines. Do not reject H0. There is not sufficient evidence to conclude that there is a significant difference between the product weights for the two lines.Reject H0. There is sufficient evidence to conclude that there is a significant difference between the product weights for the two lines.
