(a) A researcher wants to determine if there is a linear relationship between the days of FMCO and its cases of Covid19. The following data is recorded. Days of quarantine 16 14 12 10 8 6 Cases of Covid19 400 900 |2400 2800 3000 5000 (i) State the independent and dependent variable for the above data. (2 marks) (ii) Calculate the Pearson correlation coefficient. Hence, comment on the strength of the correlation between the two variables. (5 marks) (iii) Determine the coefficient of determination and discuss what its value tells you about the two variables. (2 marks) (iv) Find the linear regression equation of results on days of quarantine. Give the coefficients in two decimal places. (5 marks) (v) Estimate the results if the day of quarantine is 6 and comment on the reliability of your answer.
