Interpret the rates. b) Calculate the age-specific death rates from asthma for 1980 and 2014 and present in a single table. For one age group and year, show the formula you have used and your working. c) Calculate the directly age-standardised death rate from asthma for 1980 using the population given for 2014 as the standard population.

Direction: 1. Read each situation in the table below, then state if it is a density independent limiting factor or a density-dependent limiting factor. Indicate the specific limiting factor that is occurring (i.e, emigration, predatior., and diseases and parasites). Density independent or density dependent? Limiting factor Situation 1. Mrs. Rosales has 55 students in her biology class, but she has room for 50. Because the room was crowded, the 5 students were asked to go to the curriculum chairperson to change their schedule. 2.

Context Calculating mortality in a very small population: ⚫ 896 people in a population at mid-year • 27 deaths in the population in that year • 247 cases of diabetes in the population • 10 deaths from cancer, 8 deaths from heart disease, 5 deaths from diabetes, 2 deaths from car accidents, 2 deaths from other injuries. ⚫ Of the 896 people in the population, 234 were college students, and there were 2 deaths in that sub-population. Assignment Referring to the data above, please answer the following questions. Answers should be expressed per 1000 people, except for proportionate mortality and case-fatality, which should be expressed as a percent. Round your answers to nearest whole number. D Question 1 important information. A 1 APR 11 O pts Ը 1
Give typed full explanation The use of data from the "tick-box" on the death certificates to track work-related mortality trends is an example of which kind of surveillance system? Provide an explanation for your choice of surveillance system [3] Country A and Country B both have crude mortality rates for stroke of 6 per 1000 population per year. Country A has an age-adjusted mortality rate for stroke of 3 per 1000 population per year. Country B has an age-adjusted mortality rate of 8 per 1000 people. Which of the following are correct? [1] a) Country A has an older population than Country B b) Country A has a younger population than Country B c) Diagnosis of stroke is more accurate in Country A d) Diagnosis of stroke is more accurate in Country B
