please help me solve this math example

I don't understand what confidence interval is

thank you

A husband and wife, Mike and Jane, share a digital music player which has a feature that randomly selects which songs to play. A total of 2,384 songs were loaded onto the player, some by Mike and some by Jane. Suppose that when the player was in random-selection played, 13 out of the first 50 songs that were played were songs that had been loaded by Jane.

Construct and interpret a 95% confidence interval for the proportion of songs on the player that had been loaded by Jane. Show work.
