In which of the following situations can multiple regression be performed? Select all that apply. predicting the current salary of an employee, given the initial salary and the number of years the employee has been in his or her current position predicting the number of home runs a baseball player will hit in the next season, given the number of home runs the player hit in the previous season and the number of doubles the player hit in the previous season predicting the number of sodas sold at a concert, given the attendance at a game predicting the number of cans of chicken noodle soup sold at a supermarket, given the number of flu cases in the past month

The value α that represents the probability of type I error is often referred to as the __________________________ of the test.

When a stone is dropped in a pond, ripples are formed and travel in concentric circles away from where the stone was dropped. The equation of the least-squares regression line is log(Area) = 0.490 + 2.004 log(Time). WWhat is the predicted area of the circle, in cm2, 4 seconds after the stone is dropped? O 49.72 cm2 O 199.43 cm2 O 311.89 cm? O 1854.10 cm2
