Core Question - apologies for my ignorance

[Yendall]

For this part, it asks to apply the reciprocal transformation to the data and determine the equation. Then it states "Write the coefficients correct to two decimal places"

Now either this is a simple misinterpretation or i'm missing something.
This is what I did:

• Transformed the data:

• Plotted the transformed data as X-Reciprocal and Y:

• Determined the coefficients:

I know why this is wrong, they are asking for the equation. But, can be seen as "coefficients"? Whenever a question like this appears, when they ask for "coefficients" do you automatically assume it's the regression equation? or and ?

I know why this is wrong, they are asking for the equation. But, can be seen as "coefficients"?

Since when can and ever be considered coefficients when talking about a regression line? And will be the same as because that's what the gradient is. Although I don't know where you got from as your calculator doesn't refer to the gradient as ?

when they ask for "coefficients" do you automatically assume it's the regression equation? or and ?

I don't get how you are interpreting it like this... In the question it asks you to determine the "least squares regression line", so it is that exact phrase that makes you automatically assume they want the regression equation.

And seen as they are not referring to strength or the relationship (in terms of whether the variation in DP depends on the IV) then why would you ever consider mentioning the  and   values?

Thank you! I just over-thought and misinterpreted  the question.
