Abby and Raquel like to eat sub sandwiches. However, they noticed that the lengths of the “6-inch sub" sandwiches they get at their favorite restaurant seemed shorter than the advertised length.

Here are the actual lengths of each of the 24 sandwiches (in inches): 4.50 4.75 4.75 5.00 5.00 5.00 5.50 5.50 5.50 5.50 5.50 5.50 5.75 5.75 5.75 6.00 6.00 6.00 6.00 6.00 6.50 6.75 6.75 7.00
