What is the chi-square distribution? Explain your answer?

In words, but making use of equations where appropriate, explain how the Principal of Conservation of Linear Momentum is a demonstration of Newton’s third law of motion. In particular, consider a simple collision between two objects. The collision may be either elastic or inelastic. It may be head-on or oblique. State how the changes in motion as a result of this collision relate to Newton’s Third Law. Finally expand your reasoning to cover a many particle system.

Researchers studying the link between prenatal vitamin use and autism surveyed the mothers of a random sample of children aged 24 - 60 months with autism and conducted another separate random sample for children with typical development. The table below shows the number of mothers in each group who did and did not use prenatal vitamins during the three months before pregnancy (periconceptional period).

1) State appropriate hypotheses to test for independence of use of prenatal vitamins during the three months before pregnancy and autism.

2) Complete the hypothesis test and state an appropriate conclusion.

3) A New York Times article reporting on this study was titled “Prenatal Vitamins May Ward Off Autism”. Do you find the title of this article to be appropriate? Explain your answer. Additionally, propose an alternative title.
