2. Suppose in a city of 10 million people, fifty percent have been infected with the new corona virus.

(i) If a sample of 204 people is selected without replacement, what is the probability that at least 105 will be infected? Give an exact expression for your answer. Do not simplify.

(ii) Repeat Part (i) except assume that the sampling is with replacement. Do not simplify.

(iii) Suppose that you test the 204 people one-by-one with replacement. Consider the event E that you will observe at least 6 people in a row who test positive or at least 6 people in a row who test negative. Prove that P(E) > 0.60. [Hint: Consider adjacent non- overlapping groups of six]

Please do part (iii) only

Suppose that a test for determining whether a person has been infected with COVID-19 has a 20% rate of false positives (i.e. in 20% of applications, the test falsely indicates that a person has been infected with COVID-19 when they actually have not). Now, consider the likelihood that when 100 healthy people are tested, the test falsely indicates that between 10 and 30 of them are infected. c. Before you use the normal approximation to calculate P(10 ≤ x≤ 30),...
