It was reported that 18% of the residents of hospital-based continuing-care facilities in the province of ontario in 2004–2005 were under the age of 65. a study involving a random sample of 300 residents of such facilities is to be conducted. what is the probability that between 15 and 20 percent of the individuals in the sample will be less than 65 years of age?
