Question

you use q line of best fir for a set of data to make a prediction about an unknown value. the correlation coefficient for your data set is -0.833can you be confident that your predicted value will be reasonably close to the actual value

Answer 1

Correlation coefficients are expressed by a number between -1 and 1.

If the value is -1 or 1 it indecates a perfect (negative and positive) correlation.

If the value is 0 indicates null correlation.

As the correlation value for you data set is -0.833 it is very close to the -1. It indicates a good correlation in the data. Then, the value you predicted is reasonably close to the actual value.
