- Kk142. what is a mathematical model? What are the two basic components of a mathematical model?Suppose you reject the null hypothesis H0: μ = 58. It turns out the population mean is actually equal to 55. You have made Group of answer choices Type I and Type II errors a Type II error a Type I error the correct decisionMORE BENEFITS OF EATING ORGANIC Using data from a study, we find a significant difference in the proportion of fruit flies surviving after 13 days between those eating organic potatoes and those eating conventional (not organic) potatoes. This exercise asks you to conduct a hypothesis test using additional data from this study. In this case, we are testing where p, and p, represent the proportion of fruit flies alive at the end of the given time frame of those eating organic food and those eating conventional food, respectively. We have n₁ = n₂ = 500. Show all remaining details in the test, using a 5 % significance level. Effect of Organic Raisins After 20 Days After 20 days, 275 of the 500 fruit flies eating organic raisins are still alive, while 170 of the 500 eating conventional raisins are still alive. ¹Proportions approximated from information given in the paper. Part 1 Give the test statistic and the p-value. Round your answers to three decimal places. Ho: Po = Pc Ha: Po > Pe…
- A certain affects virus 0.4% of the population (in a population of 100,000 people, 400 will be infected with the virus). A test used to detect the virus in a person is positive 87% of the time if the person has the virus (true positive) and it is positive 14% of the time if the person does not have the virus (false positive). Fill in the remainder of the following table and use it to answer the questions below.

If the animal is in the meadows on one observation, then it is three times as likely to be in the meadows as the woods on the next observation.Assume that state 1 is being in the meadows and that state 2 is being in the woods.(1) Find the transition matrix for this Markov process.
