Fifty matched pairs ofmagnitude/depth measurements randomly selected from10,594 earthquakes recorded in one year from a location in southern California. Find the best predicted depth of an earthquake with a magnitude of 1.7. Use a significance level of 0.05.

The regression equation is

y^= ----+---x

(Round to one decimal place asneeded.)

Given that the earthquake has a magnitude of 1.7, the best predicted depth is

km.
