Hello! I can help you with this!
1. Okay. 1/2 as a decimal is 0.5 and 8/9 is about 0.89. Just by looking at the answer choices, A and B are both eliminated, because they are less than 1/2. 22/24 is about 0.92 as a decimal, which is more than 0.889. C is eliminated, which leaves us with D. 19/24 is about 0.79, which is greater than 0.5, but less than 0.89. 19/24 is between 1/2 and 8/9. The answer is D: 19/24.
2. Okay. Finding the answe to this will require converting the improper fraction into decimals, through dividing. Just by looking at the answers, we can eliminate C and D, because those denominators are odd. That will not get us to 9.5 evenly. 9.5 is also 9 ½. Let's try A. 46/5 is 9.2. 9.2 < 9.5. A is out. 19/2 is 9.5. 9.5 = 9.5. There. 9.5 is 19/2 expressed as a fraction in simplest form. The answer is B: 19/2.
Answer:
A. For the situation presented, we find that the researcher assumes that the test with the new method will obtain results at a cost of less than $ 220.
the null hypothesis will be that the operation of the new method will cost not less than $ 220.
the alternative hypothesis will be that the operation of the new method will be less than $ 220
B. With the situation of the exercise we can affirm that the null hypothesis is not rejected, since the director has verified that the cost of the new method is below $ 220, so the new method can be implemented.
C. For this situation, it is observed that the null hypothesis has been rejected, so after verification, the manager has observed that the cost of the new method is less than $ 220, so the manager's proposal can be developed.
