1. A study population of 900 inhabitants there are 50 cases of tuberculosis and 18 cases of hypertension. During the first six months there are 15 new cases of tuberculosis
and 6 new cases of hypertension. At the end of the year the total of new cases is 25 for
tuberculosis and 11 for hypertension. During the same period, 6 new cases of
tuberculosis died and 6 were cured. In the same period, 3 cases of hypertension died
and no case of hypertension was cured. Calculate the following rates
A. Prevalence rate at the beginning of the study
B. Incidence rate of tuberculosis and hypertension at the end of the first six months
C. Incidence rate of tuberculosis at the end of the year
D. Prevalence rate of tuberculosis and hypertension at the end of the year

In multiple sclerosis, the immune system destroys the substance that coats and protects nerve fibers in the brain and spinal cord. this causes inflammation and injury to the nerves, and the axons don't conduct impulses as well.

Hi i need comment on my homework or something to add. *argue for and against quantitative and qualitative techniques respectively. which ones would you lean towards when conducting an investigation and why?   quantitative techniques, usually presented through surveys, are more practical, take less time, and can design samples in which any person or household of the target audience has the same probability of participating. however, the questionnaires must be carefully written by highly trained professionals, in such a way that they do not contain ambiguous or biased questions, that they are easily understandable by any member of the sample, and that they contemplate all the objectives of the research. besides that they do not allow to deepen in the reason of the facts. qualitative techniques, on the other hand, are based on the observation of natural behaviors, discourses, open responses for the subsequent interpretation of meanings. studying reality in its natural context can be extremely useful to learn more about the phenomenon studied. however, more specialization is required, they are not applicable to statistics, so it is not possible to make measurements, it entails a higher cost per studied population (which is also reduced), whose results do not necessarily represent the general population. i believe that knowing the situation of the general population, through statistics is essential. in addition, because of the possibility of studying a much larger population in less time and with less amount of economic resources, i would lean towards quantitative research.
