Researchers are studying sales at car dealerships in two locations. The researchers are going to compute independent 90 % confidence intervals for the mean sales for the car dealerships at each location. The probability that AT LEAST one of the intervals will cover the true mean yields at that location is: O0.81. O0.99. O0,19. O0.90.
