In a recent year, 21.2% of all registered doctors were female. if there were 56,900 female registered doctors that year, what was the total number of registered doctors?

Let the total number of registered doctors = x

Given that in a recent year, 21.2% of all registered doctors were female.

so that means total number of female doctors which are registered = 21.2% of x = 0.212x

Given that there were 56,900 female registered doctors that year. so we can set both equal and get equation:

x=268396.226415

Hence final answer is that there are total approx 268396 registered doctors.

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
