A popular board game manufacturer was interested in the relationship between the amount of time it takes to play a game and how well that game is rated among board game players. Information was collected on several board games
and was used to obtain the regression equation ý = 27.273x + 18.182, where x represents the time it takes to play in
hours) and ŷ is the predicted rating of that game (in points). Which statement best describes the meaning of the slope
of the regression line?
X For each increase in rating by 1 point, the predicted hours of play increase by 18.182.
For each increase in rating by 1 point, the predicted hours of play increase by 27.273.
For each increase in hours of play by 1, the predicted rating of the game increases by 18.182 points.
For each increase in hours of play by 1, the predicted rating of the game increases by 27.273 points.

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.

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!

you can use a^2+ b^2=c^2
