Lily is a traffic engineer who is investigating the number of vehicles that travel on a certain point of expressway each day. She places a traffic counter in one direction of the expressway for 14 days. The number of vehicles counted each day are provided in the accompanying table.

15,410 16,247 16,096 16,330 17,107 11,812 14,877
14,731 15,873 16,129 16,284 16,959 12,101 14,514
Lily says that she can model the data for the number of vehicles per day to a normal distribution because the distribution is symmetric. Explain whether Lily's statement is correct, and if not, correct the statement she made.
