1. Assume a disease has a probability of infecting each individual in a population with truly random mixing with a daily value of p = 0.15. a. Produce two graphs: the first showing the time-course of the cumulative probability of being healthy and the second the cumulative probability of being diseased for 20 days. b. What is the cumulative probability of still being healthy at t = 10 days?c. If there are 1000 people in the population, estimate how many will still be healthy after 15 days.

The probability that an individual randomly selected from a particular population has a certain disease is 0.04. A diagnostic test correctly detects the presence of the disease 94% of the time and correctly detects the absence of the disease 96% of the time. If the test is applied twice, the two test results are independent, and both are positive, what is the (posterior) probability that the selected individual has the disease?

TO SU Part 1: Probability were cay 1. A question on a multiple-choice test has 10 questions each with 4 possible answers (a,b,c,d). a. What is the probability that you guess all the answers to the 10 questions correctly (carn 100%)? 2. If you ask three strangers about their birthdays, what is the probability a. All were born on Wednesday? b. What is the probability that all three were born in the same month? c. All were born on different...
Part A - SIR model for the spread of disease Overview. This part of the assignment uses a mix of theory and data to estimate the contact number c=b/k of an epidemic and hence to estimate the infection-spreading parameter b. The point is that once you know the value of b for a certain disease and population, you can use it in your model the next time there is an cpidemic, thus cnabling you to make predictions about the demand...
2) Populations versus samples. For each statement, answer with either population, sample, or both. A) The complete set of information. B) A portion, not all, of the information. C) Has the potential to be biased or misleading. D) Measured or summarized with parameters. E) Measured or summarized with statistics. 3) Descriptive versus inferential statistics. For each statement, answer with either descriptive or inferential statistics. A) Facts about samples. B) Educated guesses about populations based on samples. C) The world population...
The data of a major referral hospital showed that most patients with ischemic heart disease (IHD) were black American. Based on this, it was concluded that black Americans are at higher risk of IHD compared to other community groups. How would you describe the conclusion? A. Correct, because risk factors for IHD are more common in black African American. B. Incorrect, because no test of statistical significance has been made C. Incorrect, because prevalence is used instead of incidence D....
