Given the regression equation for the response of the reaction time in minutes to the exposure to a chemical level is Y = 2.3x – 1.8, what is the reaction to a level of 1.8?

2.34 mins

Explanation:

The regression equation in mathematical terms, shows the relationships between a dependent variable (reaction time) and one or more independent variables (exposure to a chemical level).

It also shows the effect of exposure to chemical on the reaction time.

The linear regression equation Y=2.3X-1.8 can be used to make predictions about about Y which is the reaction time for a given value of X which is the level of exposure to chemical.

From the question, X (level of exposure to chemical) is 1.8

The regression equation becomes

Y=2.3(1.8) - 1.8

Y= 4.4 - 1.8

Y= 2.34

There fore, the reaction time is 2.34 mins
