A small business owner recorded how many customers visited their online store since 8AM. However, the owner forgot to record the number of customers at 8 PM, so they created a linear model c(x) = 0.8x + 56 with a coefficient of determination of 0.04 to fit the data that was recorded.
Can they use this model to estimate how many customers visited the online store at 8 PM?
They can estimate that the store had around 66 customers since this is an interpolation and the model has a moderate fit.
They should not use this model to estimate this value since the model is a weak fit.
They should not use this model to estimate this value since the value is an extreme extrapolation.
