Tell whether the sampling strategy will result in a random sample from the population under consideration. If it is not random, explain why it is not.A radio show host would like to obtain a random sample of 5 of the 30 people who have called in with the correct answer to a quiz question. Her assistant lists their names alphabetically. She thens spins a roulette wheel which has the numbers 0-36 each of which is equally likely to come up.]She chooses the person corresponding to the number that comes up. She spins the wheel again and again chooses the person corresponding to the number. Numbers larger than 30, repeated numbers, and 0 are ignored. She contunes until 5 people have been selected and then stops.
