The following data are product weights for the same items produced on two different production lines. Line 1 Line 2 13.6 13.7 13.8 14.1 14.0 14.2 13.9 14.0 13.4 14.6 13.2 13.5 13.3 14.4 13.6 14.8 12.9 14.5 14.4 14.3 15.0 14.9 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 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 < 0H0: The two populations of product weights are identical. Ha: The two populations of product weights are not identical. Find the value of the test statistic. W = Find the p-value. (Round your answer to four decimal places.) p-value =
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.

Ha: Median for line 1 − Median for line 2 = 0H0: 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 < 0H0: The two populations of product weights are identical.
Ha: The two populations of product weights are not identical.
