A drug manufacturer claims that its new drug causes faster red-cell buildup in anemic people than the drug currently used. A team of doctors tests the drug on 6 randomly selected people and compares the results with the current buildup factor of 7.1 (this is the buildup factor for the current drug). The results of the 6 peoples are (theses are red-cell buildup factors):

6.3 7.8 8.1 8.3 8.7 9.4.

Test the manufacturer’s claim by stating the null and alternative hypothesis, then make your decision and draw your conclusions using the following methods. (Note: since this is a medical study, researchers often want to be very certain that a new drug does what it states it does. As a result, the test is often performed with a low level of significance, as is the case here, meaning that you require very strong evidence against the null hypothesis before you will reject it)

The manufacturer of a new racecar engine claims that the proportion of engine failures due to overheating for this new engine, (p1), will be no higher than the proportion of engine failures due to overheating of the old engines, (p2). To test this statement, NASCAR took a random sample of 225 of the new racecar engines and 215 of the old engines. They found that 27 of the new racecar engines and 16 of the old engines failed due to overheating during the test. Does NASCAR have enough evidence to reject the manufacturer's claim about the new racecar engine? Use a significance level of α=0.05 for the test.

Step 1 of 6 : State the null and alternative hypotheses for the test. ep 1 of 6 : State the null and alternative hypotheses for the test

There are numerous empirical studies that provide evidence that the birth of children influences both a mother’s and father’s labor force participation. Use the theory of labor force participation of individuals to explain this relationship. Do you think that the birth of a child will have a positive or negative effect on the mother’s labor force participation? What about on the father’s labor force participation?

With respect to the dividend discount model (constant and nonconstant forms), net present value model, FCF enterprise value model, etc., it has been suggested that the complexity is not the actual formula but the inputs. Use the constant growth dividend discount model (P = D / r – g) to explain why—and what about—the complexity of the inputs is key to the analysis.
