A husband and wife, Ted and Suzanne, share a digital music player that has a feature that randomly selects which song to play. A total of 3476 songs have been loaded into the player, some by Ted and the rest by Suzanne. They are interested in determining whether they have each loaded a different proportion of songs into the player. Suppose that when the player was in the random-selection mode, 22 of the first 30 songs selected were songs loaded by Suzanne. Let p denote the proportion of songs that were loaded by Suzanne. State the null and alternative hypotheses to be tested. How strong is the evidence that Ted and Suzanne have each loaded a different proportion of songs into the player?
