A film buff has formed the vague impression that movies tend to be longer

A film buff has formed the vague impression that movies tend to be longer than they used to be. Are they really longer? Or do they just seem longer? To investigate, he randomly samples U.S. feature films made in 1956 and U.S. feature films made in 1996, obtaining the following results:

 

Do these data provide convincing evidence that 1996 movies are longer than 1956 movies? Compute a significance probability that may be used to encourage or discourage the film buff’s impression. Explain how this number should be interpreted. Identify and defend any assumptions that you made in your calculations.
