Q5. A patient is given an 5 fluid drip, and the concentration of the fluid in his blood is measured in appropriate units at one-hour intervals. The doctors expected that a linear relationship exists between the variables. The following information was discovered: 8 Time, x (hours) 0 1 2 3 4 5 6 7 Concentration, y| 2.4 | 4.3 | 5.0 | 6.9 | 9.1 | 11.4 | 13.5 | 15.1 | 16 | Calculate the linear regression coefficients bo and b, for this data. (a) (b) (c) (d) CONFIDENTIAL (e) Write the fitted simple linear regression model for the above data. (f) Find the concentration of the fluid at 3.5 hours. BIC 10603 (10 marks) Compute the coefficient of correlation. (1 mark) (2 marks) CONFIDENTIAL Find how long it would be for the concentration reaches 8 units. State your answer in hours, minutes and seconds. (2 marks) (3 marks) Interpret the sample correlation between time and concentration based on Q5(e). (2 marks)
