This is two variable statistic- grade 12 data management - critical analysis/ cause and effect can someone please answr and thanks

3. In statistics, it is understood that one never calculates the equation of the regression line and the corresponding correlation coefficient without the accompanying scatterplot. Give two reasons why. [2] 4. A set of data has a linear correlation of 0.21. Despite the low number give two reasons why there might still be a strong relationship between the variables. [2] 5. The following chart shows how the population of a town has been growing over the past 10 years Number of Years 0 2 6 10 Population (1000s) 15.2 20.2 27 35.6 47 61.5 a) Using technology, create a scatterplot. Would a line of best fit or a curve of best fit be better? [1] b) Using technology, state the equation for a curve of best fit and the coefficient of determination. [2] c) Take a screen shot or use some sort of snipping tool to include your scatterplot with the table of values and the equation information. [2]
