10 E The regression line that gives the linear relationship between the magnitude of the earthquake and the number of people killed is predicted number of people killed=-114 + 35.4(magnitude of the earthquake). Which of the following is the correct interpretation of the intercept of this regression line? If the magnitude of the earthquake increases by 35.4, then the predicted number of people killed decreases by 114 If the number of people killed is O, then the predicted magnitude of the earthquake is -114. If the magnitude of the earthquake is 0, then the predicted number of people killed is -114 If the magnitude of the earthquake is 0, then the predicted number of people killed is 35.4 If the magnitude of the earthquake is 35.4, then the predicted number of people killed is -114

The regression line that gives the linear relationship between the magnitude of the earthquake and the number of people killed is predicted number of people killed = -114 + 35.4(magnitude of the earthquake). Which
of the following is the correct interpretation of the intercept of this regression line?
If the magnitude of the earthquake increases by 35.4, then the predicted number of people killed decreases by 114
If the number of people killed is O, then the predicted magnitude of the earthquake is -114.
If the magnitude of the earthquake is 0, then the predicted number of people killed is -114
If the magnitude of the earthquake is 0, then the predicted number of people killed is 35.4
If the magnitude of the earthquake is 35.4, then the predicted number of people killed is -114
