A recent article in the Journal of Urban Chicken Farmers reported the fraction of chickens thatexperience severe, moderate, or minor side effects from a new diet are 0.07, 0.15, and 0.78respectively. Assuming that chickens respond independently, if 18 chickens were tested on the new diet,what is the:3.a. Mean number of chickens that will suffer severe side effects?b. Variance in the number of chickens that will suffer severe side effects?C.Conditional mean of the number of chickens that suffer severe side effects given that 17suffer minor side effects.

a. Let A denote the number of chickens that experience severe side effects from a new diet. The…

The Economist collects data each year on the price of a Big Mac in various countries around the world. The price of a Big Mac for a sample of McDonalds restaurants in Europe in May 2009 resulted in the following Big Mac prices (after conversion to U.S. dollars):3.80 5.89 4.92 3.88 2.65 5.57 6.39 3.24The mean price of a Big Mac in the U.S. in May 2009 was $3.57. For purposes of this exercise, assume it is reasonable to regard the sample as representative of European McDonalds restaurants. Does the sample provide convincing evidence that the mean May 2009 price of a Big Mac in Europe is greater than the reported U.S. price? Test the relevant hypotheses using a = .05.

Can you please help me answer the following as I got this incorrect on my assignment: Question: Relate to this specific scenario: What is the null hypothesis? What is the alternate / research hypothesis? Which one do you statistically assess? My answer that was marked incorrect: The null hypothesis states that there is no difference or correlation between a person's heart rate and exam score. The alternative: A person's heart rate and predicted test score are related. An inferential statistical test is performed on the null hypothesis. Professor feedback to change and resubmit: not either of these words is most appropriate - scenario states prediction To measure whether test performance can be predicted based on one’s anxiety, a researcher asked his students to come to the lab 15 minutes before they were to take an exam in his class. The researcher measured the students' heart rates and then matched these scores with their exam performance after they had taken the exam. Use the…
