Suppose that 65% of all registered voters in a certain area favor a 7-day waiting period before purchase of a handgun. Among 285 randomly selected voters, determine the approximate probabiliti below. (Use the approximating normal distribution. You may need to use a table. Round your answers to four decimal places.) USE SALT (a) What is the approximate probability that at least 190 favor such a waiting period? 0.2901 (b) What is the approximate probability that more than 190 favor such a waiting period? 0.2796 (c) What is the approximate probability that fewer than 170 favor such a waiting period? 0.0332 x
