Question

The relationship between commercial airtime minutes and an advertiser's profits is given by the least squares regression equation:

                    y = 5113.84*x + 406,755

What is the predicted change in profits for each 10 minute increase in airtime?

$457,893.40

$ 51,138.40

$411,868.84

$ 5,113.84

Seismic tremors causing minor fluctuations in a delicate process may be an example of:

an assignable cause of variation

an external failure

statistical process control (SPC)

a common cause of variation

This is the question plz help

Answer 1

If the equation is y=5113.84x+406755

Which means for each minute's increase, the profits change by 5113.84

And so for each 10 minutes, the profits increase by

Seismic tremors causing minor fluctuations in a delicate process may be an example of:

An assignable caused of variation because we know a change occured due to an identifiable external factor
