Question

An analysis of the decay of 10 grams of an unstable element over time was completed and is displayed in the computer output.

Answer 1

The equation of the least-squared regression line is: In(Element) = 2.305 - 0.101(Time).

What is a regression line?

A regression line displays the connection between scattered data points in any set. It shows the relation between the dependent y variable and independent x variables when there is a linear pattern.

According to the given problem,

From the table we can see,

ln(Element) is the dependent variable and Time is the independent variable.

The constant = 2.305,

Time = -0.101

Hence, we can conclude, our least squared regression line will be

In (Element) = 2.305 - 0.101 (Time).
