2. Within some populations the proportion of those who are carriers of the sickle-cell trait is estimated to be 30%. A public health officer on a Caribbean island wonders whether this estimate is correct for the citizens of that island. Assuming that it will be a random sample, he requests that the next 150 blood tests performed in a certain clinic also include a microscopic examination for the sickling phenomenon.
