At Oakton, Midlothian, and Jefferson high schools, the long jumpers employ different strategies for competition. At Oakton high school, the jumpers are very conservative. They are always very careful not to fault, which would result in a jump of 000. But as a result they all jump similar short distances. At Midlothian, the jumpers are very aggressive. They jump as far as they can, but they risk faulting. About half the jumpers get a score of 000 and half jump long distances. (A "long distance" is about twice as far as a "short distance".) At Jefferson, the jumpers strike a balance. They are fairly aggressive, but also careful. As a result, most jump medium distances, while one or two of them fault and jump 000. At Oakton, the median jump will likely be the mean. Suppose 777 out of 151515 jumpers faulted at Midlothian. At Midlothian, the median jump will be the mean. At Jefferson, the median jump will likely be the mean.

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.

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse
