'latent' stage correct answer The period between exposure and infection is called 'latent period', since the pathogen is present in a 'latent' stage, without clinical symptoms or signs of infection in the host. 5 W of epidemiology: correct answer What is the health related state such as the disease Who describes the person that are affected by the health event Where is the place that it occured When is the time Why is all about the cause Age of degenerative and man-ma...

A 95% confidence interval for a mean indicates A. 95% of the observations are located within the interval B. there is a 95% chance that the finding is statistically significant C. We can be 95% confident that the true population mean lies within the interval D. All of the above correct answer c. We can be 95% confident that the true population mean lies within the interval A 95% confidence interval for the mean of a set of height measurement is 62.9 and 64.5 inches. This finding means t...
