Explanation Weight is the magnitude of how heavy an object is. The units to measure weight that are used most often in the U.S. measurement system are the ounce, the pound, and the tonne. Relation between the units: 16 ounces ( o z ) = 1 pound ( l b ) and 2000 pounds = 1 tonne ( t o n ) . The smallest unit is ounce while the largest unit is tonne. Unit fractions: 16 oz 1 lb = 1 lb 16 oz and 2000 lb 1 ton = 1 ton 2000 lb . In this question two quantities have to be subtracted. Given two numbers, it is possible to subtract one of them from another and their difference is a new number. The difference between two numbers can be calculated, but the result is not equal if the order of the numbers is changed. The condition to maintain while subtracting two numbers is that they must be represented in the same unit. There are two ways of subtraction when the two given numbers are in different yet relatable units. One way is to convert one or both of the numbers into the same unit before performing the operation, while the other way is to consider the relation between the place values and thereafter continue with the operation using the face values. While using the second method, priority should be given to the lower face value. During the operation subtraction, the face values at lowest place value are subtracted. If the place value of the number which is subtracted is more than the number from which the subtraction is performed, one unit of the immediately next higher place value is added to the corresponding face value from which the subtraction is being done and the complete face value is added to it. This creates the concept of “borrowing”. This process is repeated till the highest available place value is utilized. In the given question, the place values are described by the units ton and lb given as below in the decreasing order of their place values: tonne (ton) pound (lb) According to the discussion earlier, subtraction has to be performed first for lb and then for ton

3. Explain why the following statements are not correct. a. "With my methodological approach, I can reduce the Type I error with the given sample information without changing the Type II error." b. "I have already decided how much of the Type I error I am going to allow. A bigger sample will not change either the Type I or Type II error." C. "I can reduce the Type II error by making it difficult to reject the null hypothesis." d. "By making it easy to reject the null hypothesis, I am reducing the Type I error."
