While building his catapult, Aiden tested several different designs. He varied the arm length of his catapult and recorded the horizontal distance between where the ball was launched and where it landed for each arm length. The table presents Aiden's data showing the length of the catapult arm in relation to the horizontal distance the catapult launched the tennis ball.

Length of catapult arm (cm) Horizontal Distance (cm)
60 320
80 352.4
100 386.8
60 288.1
70 315
75 322
90 362
100 390
85 350
95 398
What is the equation of the line of best fit for Aiden's data?
Enter the correct answer in the box by replacing m and b in the equation. Round each number to the nearest tenth (this equation over here) y=mx+b

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.
