b. In a certain chemical process, the reaction time is related to the temperature in the chamber in which the reaction takes place. The reaction time (minutes) and the temperature ( C) is observed. The results from a randomly selected sample are shown in Merosoft Ofce Excel output as follows: ii. iii. iv.

(lmark) State the equation of the tted linear regression model of reaction time against temperature. (2 marks) Is there any signicant evidence that the data support the existence of a linear relationship beMeen reaction time and temperature at 5% signicance level? Briey, justify your reasoning. (2 marks) State the measured strength of relationship between reaction time and temperature. and comment on the relationship. (2 marks)
