A public opinion poll in Southern California was conducted to determine whether Southern Californians are prepared for the “big earthquake” that experts pre- dict will devastate the region sometime in the next 50 years. It was learned that "60% have not secured objects in their homes that might fall and cause injury and dam- age during a temblor." In a random sample of n = 864 Southern Californians, let X equal the number who "have not secured objects in their homes." Find P(496 ≤ X ≤ 548), approximately.
