Chapter 1, Problem 1E
In addition to the key words that were defined in the text, you should be able to define the following terms, which also appear in the glossary:
Replication
Pseudoscience
Expert Solution & Answer
To determine
Define the term Replication and Pseudoscience
Answer to Problem 1E
Solution:
Replication is used in order to cheak the correctness of the answers. Psuedoscience is a blind belief of unscientific facts as scientific.
Explanation of Solution
Replication:
In scientific experiment behavior, a procedure is done repeatedly in order to attain accurate results. When a single procedure is done many times and the result is same then the scientist confirms that their study is correct. And it is also done to determine the original study can be applied to another research procedure.
Pseudoscience:
It deals with unscientific facts mistakenly considered as scientific. This is because there is no strong evidence to prove that it is wrong or no proper experiment was done on it to prove it is scientifically wrong. For example, in 2012 it is believed that the whole world is going to end, but it's not the actual fact.
Conclusion:
Replication is used to check the accuracy of the findings. And pseudoscience is unproven scientific facts.

1- Let A = {A1, A2, ...), in which A, A, = 0, when i j.
a) Is A a π-system? If not, which element(s) should be added to A to become a π-system?
b) Prove that σ(A) consists of the finite or countable unions of elements of A; i.c., A E σ(A) if and
only if there exists finite or countable sequence {n} such that A = U₁An (Hint: Let F be such
class; prove that F is a σ-filed containing A.)
c) Let p ≥ 0 be a sequence of non-negative real numbers with Σip₁ = 1. Using p₁'s, how do you
construct a probability measure on σ(A)? (Hint: use extension theorem.)
2- Construct an example for which P(lim sup A,) = 1 and P(lim inf An) = 0.
In a town with 5000 adults, a sample of 50 is selected using SRSWOR and asked their opinion of a proposed municipal project; 30 are found to favor it and 20 oppose it. If, in fact, the adults of the town were equally divided on the proposal, what would be the probability of observing what has been observed? Approximate using the Binomial distribution. Compare this with the exact probability which is 0.0418.

You will use a single test car, adding weights so that its total weight is 3000, 3500, or 4000 pounds. The car will drive on a test track at each weight using each of Amoco, Marathon, and Speedway gasoline. Which is the best way to organize the study? Start with 3000 pounds and Amoco and run the car on the test track. Then do 3500 and 4000 pounds. Change to Marathon and go through the three weights in order. Then change to Speedway and do the three weights in order once more. Start with 3000 pounds and Amoco and run the car on the test track. Then change to Marathon and then to Speedway without changing the weight. Then add weights to get 3500 pounds and go through the three gasolines in the same order.Then change to 4000 pounds and do the three gasolines in order again.
