- Compare how the population size influenced the death toll, immunity, and contagiousness levels of influenza and the red death. In your response, you MUST USE ALL THE DATA( NUMBERS). I have to post this again because you disnt follow directions you were supposed to COMPARE THE NUMBERS IN THE DATA FOR EACH DISEASES. And you are supposed to use ALL THE NUMBERS.There are two tests for a disease, one is rapid and the other is slow. Given that an individual is infected, the rapid test will register positive 40% of the time, while the slow test will register positive 80% of the time; additionally, both tests will be positive 35% of the time. Suppose in the above example that people not infected always test negative for both tests. Suppose in the above example that people not infected always test negative for both tests. 5. Of the people in the population who are tested, 75% of their results from the slow test are positive. What is the chance that a persons has the virus conditioned on getting negative result on the slow test?A scientist claims that pneumonia causes weight loss in mice. The table shows the weights (in grams) of six mice before infection and two days after infection. At alphaαequals=0.10, is there enough evidence to support the scientist's claim? Assume the samples are random and dependent, and the population is normally distributed. Complete parts (a) through (e) below. Mouse 1 2 3 4 5 6 Weight (before) 22.9 19.1 23.6 21.2 23.2 21.7 Weight (after) 21.4 18.3 22.9 20.9 22.1 20.8 (a) Identify the claim and state Upper H 0H0 and Upper H Subscript aHa. What is the claim? A. Pneumonia causes weight loss in mice. B. Pneumonia causes weight gain in mice. C. Weight loss causes pneumonia in mice. D. Weight gain causes pneumonia in mice. Let mu Subscript dμd be the hypothesized mean of the difference in the weights (beforeminus−after). What are Upper H 0H0 and Upper H Subscript…
- Which type(s) of reservoirs are the hardest to control & make some diseases impossible to eradicate? Question 13 options: a) animals b) humans c) environmentYou sliced an apple with a knife that you also used to cut chicken breast into pieces. Your testing afterwards determined that Campylobacter jejuni bacteria were present on the knife at a population density of 1x103/ml. You would expect that this bacterial population would: a. not increase if you stored the apple slices in a jar containing 40% ethanol (ethyl alcohol) b. not increase if you stored the apple slices in a jar containing 5% acetic acid (vinegar) c. make you sick if you ate the apple slices after sitting out at room temperature for 15 hrs d. be killed by properly sterilizing and canning the apple slices e. ferment sugar in the apples into alcohol, producing a “Holiday Bowl” that is 20% ABVDoes this epidemic curve suggest a point source or propagated epidemic? Justify your answer. What does the "moving averages" (black line) represent? bruefly explain this term in relation to the concept of "variability"?
- The image attached of 100 squares represents a population of people that was stable in size and followed for 2 years for the emergence of a disease. Blue squares represent people in the population that were unaffected by disease over the whole study period. Red squares represent people in the population identified as having disease at the start of the study. The yellow squares were people in the population that were disease free at the start, but developed disease in the subsequent 2 year period. Assume everyone survives to the end of the study period whether or not they develop disease. 1) Based on the image and study description above, what was the prevalence of disease in the population at the start of the study? A) 0% B) 36% C) 38% D) 62% 2) Based on the image above and study description, what was the 2-year cumulative incidence of new disease over the study? A) 26.0% B) 62% C) 40.6% D) 36% 3) Based on the image above and study description, what is the…Log Nt = Log N0 – t/D. D is the time required for a log kill. A single dose of mouthwash is added to a bacterial culture with 10 million cells/mL and, after 30 minutes, one hundred thousand viable cells/mL remain. How many would survive at the end of 1.5 hours? Based on the equation, can you ever totally decimate the population? In a practical sense, when would you assume that all the cells are dead?You are an analyst in the Florida Department of Health and you are tasked with using the SEIR model for computing the spread of various infectious diseases in Florida.
